1) What Personal Data Do We Collect, for What Purposes and What Data Do We Share with Others?

During your visit to our Site we collect information ("data") from You, some of them is considered personal, which means they can be used to identify You as a natural person directly or indirectly - in combination with data from other sources. We collect the following data, including, IP address, cookies, various online identifiers, a page You've visited on the Site, time of your visit, your OS, your ISP provider, number of clicks on an ad presented to You, your geolocation.

Applicable Privacy laws in many countries treat that data as a personal data, and a user of the data must abide by applicable Privacy laws, consequently, an end user enjoys certain Privacy rights.

Besides getting the data during your Site visit we may obtain certain personal information in the direct communication with You for e.g. through email messages, if the need arises.

So, the data are collected by us directly or can be collected by third party vendor services also, that are present on our Site, for e.g. through ads or through our use of the website analytics service.

We use various technologies to collect and preserve your information, including cookies and similar technologies (collectively, cookies), server logs and data bases.

We Use Collected Personal Data for the Following Purposes:

  • Providing our Site to You - this includes providing web content to You, Site managing; also, managing IT and security systems (Site hosting), monitoring of such systems in order to provide uninterruptible Site running, protect our Server, Server data, user data and other entities on the internet; we consider all these purposes our legitimate interests, not overridden by your rights; we usually collect the data in our Server logs: the data are collected during your visit and interaction with our Site, including, your IP address, cookies, coarse IP geolocation (country-level), date and time of access, device OS, name of the Site page You've accessed, time spent on the page, terms you are looking for on our Site. Our hosting provider is Linode (USA), they lease to us virtual private server ("VPS" or "bare metal server"); as Linode is an unmanaged infrastructure provider, it does not collect or process any of our internal data of our end users.
  • The Site analytics - we may use the data to analyze the traffic on our Site, so we can make the Site improvements; for this purpose, we use the Google service: Google Analytics. When we use the Google analytics, we use the option for anonymizing of an end user IP address on the Google end. This tool give us consolidated reports and graphs, aggregated data, not linked to a specific natural person; types of personal data collected: online identifiers, including, cookie identifiers, internet protocol addresses and device identifiers; client identifiers; that data is stored in an anonymized form on Google servers.
  • Publishing ads on the Site - to sustain our Site we may use the ads publishing platform, Google AdSense, besides regular ads. When we use AdSense we opt to show only non-personalized ads to all our users, along with the Google's Restricted Data Processing mode, which means that the ads shown on the Site are based on the Site content and coarse IP geolocation (city-level) of a user, and not on the user profile and her interests (we're not using "interest based advertising"); Google acts in this case as an independent controller, beside us; the controller role by itself imposes greater responsibility for the collected data but gives more control over the collected data; Google says on this subject: "Google's uses of data continue to be controlled by the terms of its contract with its publishers, and any feature-specific settings chosen by a publisher through the user interface of our products."; data collected: including, cookies and similar online identifiers, such as advertising ID, IP address, pages You've visited; Google store in server logs: records of ads they serve, a user's web request, browser type, browser language, the date and time of the ad request, and one or more cookies or an advertising ID that may uniquely identify that user's browser or mobile device. Google anonymize IP addresses in logs by removing part of the address after 9 months. After 18 months, they further anonymize log data by removing cookie or advertising ID information in both logs and ad serving databases. User profile information associated with advertising cookies and advertising IDs is also stored in databases that can be accessed for ads serving in real-time. Data stored in these databases is either deleted or anonymized after 18 months. User data tied to cookies and advertising IDs is also used to detect and prevent ad fraud and ensure that users don’t see ads that they’ve blocked in the past. In these cases, or in cases where Google stores this data on behalf of its customers (e.g. users of Google Analytics), data may be stored for periods longer than those specified above. We don't link Analytics and AdSense products. Read more about this topic in Google Ads User Data Retention Policy. The data is stored on Google servers.
  • Communicating and interacting with You in relation to the Site - this mostly regards to communications realized via email messages, but doesn't exclude other communication channels; when You contact us directly, e.g., making an inquiry or giving us feedback about our Site, we may receive additional information about You including, your email address, name, and any other information considered personal information. Also, if the need arises we may ask You for additional personal information, whose purpose will be made clear to You at the point we ask for it. The information we get from You will have been kept only during ongoing conversation for the purpose we've agreed on and with your explicit permission; we may use your data, including your email address, your name, your message; the data is stored temporarily on servers of our email service providers: Google Gmail and asmallorange.com.
  • Legal requirements - we may share your personal Information with outside parties if we have a good-faith belief that access, use, preservation or disclosure of the information is reasonably necessary to meet any applicable legal process or enforceable governmental request; to enforce applicable Terms of Use, including investigation of potential violations; security or technical concerns; or to protect against harm to the rights, property, or safety of our users or the public as required or permitted by law. Legitimate interest and Legal obligation could provide a lawful basis for such processing of data.
  • Change of owner - in the event we undergo a business transaction such as a merger, acquisition by another company, or sale of all or a portion of our assets, your personal Information may be among the assets transferred. You acknowledge that such transfers may occur and are permitted by this Privacy Policy, and that any acquirer of our assets may continue to process your personal information as set forth in this Privacy Policy, with an obligation to notify users about possible Privacy changes. We consider this our legitimate interest.
  • Partners and service providers ("providers") of our service providers - most service providers also have their partners and providers, who, according to our providers' policies, abide by applicable privacy laws and our providers' respective privacy policies and their mutual agreements. We don't have insights into or control over our providers' providers and partners and their privacy practices and we are not responsible for them.

We do not combine the data that we store on our Server with the data from other sources (for e.g. 3rd party services which collect data from our end users) and we do not infer conclusions from that data, for e.g. to make personal user profiles and to predict a user's future interests with a goal to tailor an offer to her interests.

Also, we do not sell or share the data we collect and store on our server.

Also, we don't possess enough data, nor means, to personally identify any of our end users.

We don't have any kind of registration on our Site, nor we use Social networks. Also, we do not practice any kind of direct marketing, including email marketing.


What Personal Data Do We Share with Others and for What Purposes?

When we use 3rd party services on the Site, from selected service providers (i.e. data processors), they collect our end user data for certain purposes and store them on their storage units for a limited time, e.g., services like Google Analytics, AdSense, as afore-mentioned.

So, we share the user data with the service providers for specific purposes we agreed on (e.g., hosting, web analytics, publishing ads, email service) and as specified in this Policy.

The providers collect the data from our Site end users and process them on our behalf via various technologies, including their own cookies or similar technologies for data collecting and transfer. We do not combine that data with any other data that we possess, nor we make inferences ("user profiling") from them.

You can find more information about our service providers, how they process your data (see their privacy policies), how You can opt-out of them completely or how to reduce their impact on your privacy, in the sections of this document named: "Our Service Providers", "Cookie Notice", "CCPA Notice" and "GDPR Notice".

2) International Data Transfers

Our Site is hosted on the leased Server located in the USA; thus, your personal data can be processed in the country which is not your residency. So, we may transfer your personal data to other countries that may have different laws and data protection compliance requirements to those that apply in your country. No matter where your data is processed, we implement the same level of protection published in this Privacy Policy.

We always use HTTPS protocol (used for secure communication over a computer network, data in transit is encrypted) for the data in transfer between your computer and our Server, as a safeguard.

Also, we try to choose service providers, like Linode or Google, who apply certain legal frames regarding the data-transfer security, including EU-U.S and Swiss-U.S. Privacy Shield, which are a legal mechanism to enable the transfer of personal data from the EEA and Switzerland to the U.S. securely, the mechanism to comply with EU data protection requirements when transferring personal data from the EU to the USA in support of transatlantic commerce.

Regarding the data transfer to third parties, such transfers may also be under the EU Commission's model contracts for the transfer of personal data to third countries i.e., the Standard Contractual Clauses, which should give your personal data the same level of protection they have in your country.

Following service providers are certified under the Privacy Shield agreement:

3) Our Service Providers

We believe that each of our partners and service providers abide by mutual agreements, applicable privacy laws and their privacy policies. When we use service providers from the USA, such as Linode or Google, we may transfer a user personal data to them. Please see the section: "International data transfers".

Currently, Our Service Providers Are:

  • Linode International Services Company, part od Linode LLC ("Linode")

    Linode is an American company and it's our Server provider. The Server we lease from them is a precondition that we can provide our Site to the public. As Linode is an unmanaged infrastructure provider, it does not collect or process any of our internal data of our end users.

    You can read more about Linode's personal data practices in their Privacy policy and Terms of service (multiple documents, including the general terms and conditions: Master Service Agreement and Data processing Addendum). If You want to know more about the methodology of how data is Processed by Linode, see Data processing Addendum.

  • Google Ireland Ltd. Part of Google LLC ("Google")

    Google LLC is an American multinational technology company that specializes in Internet-related services and products. Currently, we may use their products/services:

    • for the Site analytics: Google Analytics,
    • for the ads publishing service: Google AdSense ("AdSense"), and
    • for email service: Google Gmail ("GMail").

    In the countries where we show Google ads, we show only non-personalized ads because they do not use technologies that track user's behaviour across websites and do not create the user personal profile.

    In the countries where we use Google Analytics, we apply the Google setting that anonymize a user IP address on the Google's side, thus, contributing to the user's personal data anonymization.

    When we use Google Analytics and AdSense, they can, through our Site, collect personal data from our Site end users by using online technology tools including their own cookies, web beacons and similar technologies (together, "cookies"), and process it.

    Google should use the data only for the purposes we've agreed on.

    Read more about how Google manages data in its ads products at how Google uses your personal data from sites and apps that use their services and read their privacy policy.


    We May Use Google Analytics

    Google Analytics provides website analytics reports to us, based on the data it has collected from our Site users. The reports only show aggregated data. Google anonymizes ip addresses of the users they've collected from our Site.

    Read the Google Analytics privacy document for more details about the data collected by Google Analytics.


    How to Opt-out from Google Analytics

    Google Analytics supports an optional browser add-on that - when installed and enabled - disables measurement by Google Analytics for any website You visit, including ours, but only for the device and browser You are currently using (for another device or browser You need to do the same). This is the preferred means to stop the Analytics. The add-on prevents the Google Analytics JavaScript (gtag.js, ga.js, analytics.js, and dc.js) that is running on websites from sharing information with Google Analytics about your visit activity.


    We May Use Google AdSense

    AdSense is the Google's ads publishing platform. We may use it for publishing ads on our Site.

    Although, Google provides the service to us, they also act as an independent controller on our Site, beside us, which draws their larger responsibility regarding the personal data they collect from our Site, but also gives them more control over the data collection. Google says on this subject: "Google's uses of data continue to be controlled by the terms of its contract with its publishers, and any feature-specific settings chosen by a publisher through the user interface of our products."

    AdSense collects the data through various technologies including cookies and one-pixel images.

    Important thing is that we do not allow showing Google AdSense Personalized ads to our users, thus, preventing "tracking cookies", which track the user's behaviour across visited websites. Preventing ads personalization has a good impact on the user privacy. The ads shown on our Site are non-personalized ads, solely based on the current Site content and coarse ip geolocation of the user. Also, we've disabled all 3rd party AdExchanges, that Google uses in AdSense, excluding the ones owned by Google.

    Google's controls for publishers, although enable us to exclude 3rd party AdExchanges (what we've already done), are not designed to cover click-tracking technologies. This means that advertisers can choose to use third-party click-tracking technologies (i.e. where an ad click directs the user's browser to a third-party measurement vendor on the way to the advertiser's landing page). They must do so in compliance with applicable law. We have no control over these 3rd party measurement vendors.


    Opt-out of Google Ads Personalization

    We do not show Google personalized ads on our Site. Besides this, we apply Google's "Restricted Data Processing" (RDP) mode, that uses additional measures regarding the user privacy.

    If You want to be absolutely sure, You can turn off Google ad personalization with Google's Ads Settings. The settings are saved to your Google Account (if you're signed in), or to your browser (if you're not signed in). These settings apply when you're using this browser and device (on another device it's necessary to do the same). These settings pertain to all websites that use AdSense ads (not only to our Site).

    Another, more preferred way to stop personalized ads is to install the Google browser plugin to keep your preference to opt-out of personalized ads from Google, even if you've cleared your cookies. Learn how to install the browser plugin.

    This doesn't mean that You'll not see any ads from Google, but the ads You'll see will be based on the website content and your general location (city-level IP geolocation), except when You use your mobile device, then it might be your precise location (You can control this feature on your device).

    Google has made commitment to its users, that it'll never sell your personal information and it gives users transparency and control over their ad experiences via tools like My Account, Why this Ad, and Mute this Ad. Learn more about how Google ads work and Why you're seeing an ad from Google.


    We May Use Gmail - Google Email Service

    Gmail is a free email service developed by Google which we may use for the communication with our users. You can read more about their personal data practices in their Privacy policy and Terms of service.


    Google Data Management

    Google may store and process Personal Data in the United States of America and any other country in which Google or any of its Subprocessors maintains facilities.

    Google data retention practices is described at policies.google.com/technologies/ads.

    Transfers of Data - Google will ensure that the parent company of the Google group, Google LLC, remains self-certified under Privacy Shield.

8) Cookie Notice

What Is a Cookie?

The cookie is a piece of information stored on a user's computer ("device") that may contain various sort of data related to the user, her device or browser. Session cookies are not permanent, once you close your browser, this type of cookie is automatically erased. A persistent/permanent cookie is another type of cookies, stored on your computer for an extended, but limited period. You can erase these cookies any time.

Besides dividing cookies by their lifetime on the user computer, the cookies can be further divided into two groups, determined by the relationship between a party that place a cookie and a website user:

  • first party ("1st party") cookies - these are cookies used directly by the website (1st party) that user visits;
  • third party ("3rd party") cookies - these are cookies used by other entities/services (3rd parties) present on the website that user visits; these other entities place their own cookies, called 3rd party cookies, upon approval of the website owner. For example, these could be cookies from Social networks (e.g.,Facebook, Twitter) or Google (Analytics and AdSense).

Besides cookies, there are other online technologies used for the user behaviour tracking and data collecting, including, web beacons, pixel tags, local storage, scripts and other tools (together, "Cookies"), used in connection with a website.

Our Site Cookies

Our Site uses the session cookie, non-permanent cookie, to remember user's preferences and other data while the user is visiting the Site. When the user close her browser the session cookie is deleted. It may contain various data related to regular Site functioning.

3rd Party Cookies - Cookies Used by Our Service Providers or Partners

Because we may use services on our Site from various service providers, they also may place cookies on your device. Google products we may use on the Site also use cookies: Google Analytics (for web analytics) and Google AdSense (for ads publishing).

Google can place on and read cookies from your browser. The cookies will send them your information including IP address, ISP, unique ID (pseudo ID), location (IP geolocation or precise location if You use mobile device), the browser type you've used to visit our Site, and in some cases, whether you have Flash installed. The information collected from our end users is used by Google for the purpose of providing the web analytics and publishing ads services to our Site. Google says it doesn't sell your information.

Google Analytics Cookies

Google Analytics is Google's analytics tool that helps website and app owners to understand how their visitors engage with their properties. Google Analytics may use a set of cookies to collect information and report site usage statistics without personally identifying visitors to Google. The user IP address is anonymized on the Google end, when we use Google Analytics.

The main cookie used by Google Analytics is the '_ga' cookie. We've truncated its default expiration time from two years to 60 days.

Learn more about Analytics cookies and privacy information.

We use analytics.js, Google JS library and it uses the following cookies:

Cookie Name Expiration Time Description
_ga 60 days Used to distinguish users.
_gid 24 hours Used to distinguish users.
_gat 1 minute Used to throttle request rate.
AMP_TOKEN 30 seconds to 1 year Contains a token that can be used to retrieve a Client ID from AMP Client ID service. Other possible values indicate opt-out, inflight request or an error retrieving a Client ID from AMP Client ID service. We don't use it.
_gac_<property-id> 90 days Contains campaign related information for the user. If you have linked your Google Analytics and Google Ads accounts, Google Ads website conversion tags will read this cookie unless you opt-out. Learn more. We did not link Google Analytics and Ads account. We don't use this cookie.

The analytics.js JavaScript library is part of Google's Universal Analytics and uses first-party cookies to:

  • Distinguish unique users;
  • Throttle the request rate.

AdSense Cookies

Google uses cookies or mobile identifiers to support personalized and non-personalized ads served by Google, to combat fraud and abuse, for frequency capping, and for aggregated ad reporting.

Where we use Google's ads, we use only Non-Personalized ads.

Non-personalized ads will use only contextual information, including coarse (city-level) location, and content on the current site or app; targeting of users is not based on a user profile or past behavior of the user.

In the case of advertising Google serves across the web, cookies (e.g., cookies named '__gads' or '__gac') may be set on our Site. Unlike cookies that are set on Google's own domains, these cookies can't be read by Google when you're on a website other than the one on which they were set. They serve purposes such as measuring interactions with the ads on our Site and preventing the same ads from being shown to You too many times.

You can see a list of the types of cookies used by Google and also find out how Google and their partners use cookies in advertising. Google privacy policy explains how they protect your privacy in their use of cookies and other information.

Learn more about how Google uses cookies and how Google uses data, including cookies, when you use Google partners' sites or apps.

Both Google products, when we use them, Google Analytics and Google AdSense, operate in their, so called "restricted data processing" mode ("RDP" mode), because we've set them to work this way, in Google products administrative/user interface. When these products operate in the RDP mode, Google declares itself as the Service Provider toward us (Google: "Subject to the terms of our CCPA service provider addendum, we will act as your service provider with respect to data processed while restricted data processing is enabled."). We use Google's RDP mode for all our users.

The CCPA includes certain exceptions to the definition of "sale", including transfers to "service providers".

We perform transfer of data to our Service providers, thus, we don't sell personal information.

We have reason to believe that all our Service providers abide by the CCPA law, their respective Privacy policies and mutual contracts with us.

Please note that where we use and disclose personal information for purposes related to security, fraud detection, and other similar purposes, some of your rights may be limited to the extent that they adversely affect the rights and freedoms of other consumers.

10) Additional Privacy Notice for EU+ End Users - GDPR Notice

The European Privacy Laws, including, the General Data Protection Regulation ("GDPR"), have a goal to ensure that Europeans have a certain level of privacy rights. This Additional Privacy Notice for EU+ End users - GDPR Notice, applies only to end users from EU+ countries (please, see the Definitions section in this document). It tries to provide certain information about our data processing practices to EU+ end users, in addition to the disclosures in our Privacy Policy.

In a case of any conflict between disclosures in this GDPR notice and disclosures in the rest of this Privacy Policy, the disclosures in this GDPR Notice shall prevail, regarding EU+ end users.

Based on the opinion of the European Data Protection Board (EDPB) stated in the document Guidelines 3/2018 on the territorial scope of the GDPR (Article 3), Version 2.1 from 12. November 2019:

"The EDPB also wishes to underline that the fact of processing personal data of an individual in the Union alone is not sufficient to trigger the application of the GDPR to processing activities of a controller or processor not established in the Union."

"Moreover, it should be noted that the processing of personal data of EU citizens or residents that takes place in a third country does not trigger the application of the GDPR, as long as the processing is not related to a specific offer directed at individuals in the EU or to a monitoring of their behaviour in the Union."

Owner of this website ("data controller", regarding the GDPR) is not from the Union and the data processing is performed in the third country. We do not have specific offers for the citizens or residents of the EU+ countries, nor we monitor their behaviour. Thus, we believe that the GDPR doesn't relate to us, according to the stated EDPB opinions.

We do not use Social networks and Google products i.e., AdSense and Analytics, for citizens or residents of the EU+ countries. We do not analyse personal data from EU+ users, nor we try to infer data from it, to make a user profile and use it for later offerings.

Notwithstanding, it may happen that some of the AdSense ads pass through, based on our use of the IP geolocation data to determine an end user's country, which is not 100% accurate. This is totally inadvertently, this is not our goal and it may happen only occasionally. Additionally, we do not retain information about the user's location (country) permanently. Even when we use Google AdSense ads, we show only non-personalized ads, ads that are not based on a user personal profile.

This doesn't relieve us from our duty to respect privacy rights of our end users.

European users can learn more about their privacy rights at the following places:
