_Your data is none of my business. I support your right to privacy. I make money by selling digital products, not by mining personal information._

**Preamble**
I prefer to avoid collecting data from you. I do not sell, rent or share personal information on you throughout your use of my apps or websites with third parties. In this policy I explain: what data I collect and why, how your data is handled, and your rights concerning your data.

**Responsible for processing personal data**
The person in charge for the processing of personal data within the meaning of GDPR article 4 is:

Martin Zimmermann-Lexow
App ahead GmbH
Peterstraße 44–46
52062 Aachen
Germany

**Apps**
None of my apps are tracking you. Most of them don’t collect analytics. In the few that do, analytics are only used with your consent. In those cases, I am using [TelemetryDeck](https://telemetrydeck.com/privacy/) for GDPR and CCPA compliant, fully anonymized data collection, which you can opt-out from at any time within the respective app itself. My intention behind this is to get a better understanding on how my products are used, to make informed decisions for further development, which in return will benefit you as a customer.

If an internet connection in one of my products is established, its use is described in the apps’ [Internet Access Policy](https://www.obdev.at/iap/index.html).

My apps enforce HTTPS encryption.

Legal basis for processing your data for this purpose is GDPR article 6, section 1 (a).

**TestFlights**
Some of my apps are available for beta-testing through Apple’s [TestFlight](https://testflight.apple.com) service. If you joined a TestFlight, Apple Inc. will collect and send crash logs, your personal information such as name and email address, usage information, and any feedback you submit to me through TestFlight. A list of the data that is collected and stored can be found [here](https://testflight.apple.com#information-shared-feedback). I only use this information to improve my apps. I do not share any of it with a third party. Apple may use this information to improve their TestFlight app and detect and prevent fraud. Apple retains TestFlight data for one year. To view and manage your data with Apple, including your data that is sent to Apple through TestFlight, visit [Data and Privacy](https://privacy.apple.com/). If you would like to be removed from one of my TestFlights, please contact support@appahead.studio, or leave the TestFlight yourself from within the TestFlight-App.

Legal basis for processing your data for this purpose is GDPR article 6, section 1 (a).

**Websites**
My websites do not set cookies. I am interested in only a handful of anonymized data points around my audience to learn if it’s worth putting effort into my digital offerings. Those are, for example: visitor count, most frequently visited pages, popular visitor countries or referring websites that send my visitors to my websites.

To get these insights I am using [TelemetryDeck](https://telemetrydeck.com/privacy/). A list of the data that is collected and stored can be found [here](https://telemetrydeck.com/docs/guides/web-setup/).

My websites are hosted with HETZNER. HETZNER stores visitor information in server log files, like described [here](https://docs.hetzner.com/general/company-and-policy/data-protection-at-hetzner). Those logs include, among other things, the clients anonymized IP address, the browser used, the time and date of the visit, and the system that visitors use. The retention period for server logs (including mail server logs) is seven days.

My websites enforce HTTPS encryption.

My websites may contain links to websites of other providers not affiliated with me. I have no influence on what data is collected and used by these third parties. As the collection and processing of data by third parties is naturally beyond my control, I cannot accept any responsibility for this.

**Support Interactions by Email**
When handling support requests from you via email, I collect the emails you sent to me. Those usually include your email address, metadata which may be contained in the email header and any information you provide voluntarily. This information is collected solely to help resolve your support inquiry.

I delete correspondence on resolved topics from my archive once a year, in order to have context from previous interactions which may help me to answer your future questions more quickly and accurately, or to identify broad trends in support requests, which may help me identify and solve problems with my products, unless (1) you and I have an ongoing business relationship or friendship, (2) unless you have expressly consented to further use your data and (3) unless the correspondence falls under commercial or tax retention obligations.

Like my websites, my emails are hosted with HETZNER as well.

If you would like to remove support emails you have sent, please contact support@appahead.studio.

Legal basis for processing your data for this purpose is GDPR article 6, section 1 (a), (b) and (f).

**Social Media**
I provide direct support exclusively via email. Please don’t reach out to me for support requests through social media. Although you will find me on most common social media platforms, please be aware that I don’t make the rules there. Please don’t ever share personal or sensitive information with me through social media or third-party platforms.

**Data Protection**
I use technical and organizational security measures to ensure that data is protected against loss, incorrect changes or unauthorized access by third parties. To the extent necessary for the above-mentioned purposes, only authorized persons have access to your data.

**Your Rights**
You have the right to (1) request all personal information I hold about you, (2) ask me to update or correct those informations, (3) ask me to delete it, (4) revoke the processing of your data and (5) to make a complaint with a regulatory authority.

I’m happy to help. Please contact me and we’ll sort it out.

**Future Changes**
This privacy policy may change at any time. It was last updated in February 2026.
