Türchenzauber privacy policy

This policy applies to the web app at flexavari.de/tuerchenzauber/app and to the Android app “Türchenzauber”. The German version is legally binding.

2. In short

• No account. Türchenzauber does not ask for your name or email address.
• Calendars, texts, photos, videos, drawings and drafts are stored only on your device. We run no server that receives this content and we never see it.
• No ads, no analytics or tracking, no cookies, no sale of data.
• The Android app has no internet permission.

3. Stored content

Everything you create is kept in your browser's storage (web app) or in the app's storage (Android) on your device, including a workshop PIN stored only as a salted check value. Clearing the site data or uninstalling the app deletes this content. The Android app opts out of Android's automatic cloud backup so that private content is not copied to a cloud without your choice.

You pick photos and videos with your device's file picker. Türchenzauber does not request camera or storage permissions.

4. Gift files and backups

When you give a calendar or create a backup, Türchenzauber creates a file encrypted with a code (AES-256-GCM). Without the code nobody can read it, including us. Only you send or store this file, for example via a messenger or email; the privacy terms of the app or storage you choose then apply.

5. Loading the web app (hosting)

The web app files are delivered by Cloudflare Pages (Cloudflare, Inc.). When you load them, Cloudflare processes technically necessary data such as IP address, date and time and browser information; see “Hosting und Server-Logs” in our general privacy policy. Your calendar content is not transmitted.

To start faster and, where possible, without internet, your browser keeps a copy of the app files (service worker). This copy contains only the app itself, none of your content.

6. Purchases

The test version contains no purchases. If paid features are added later, we will update this policy first.

7. Children

Calendars are created and given by adults. Recipients, including children, can open a calendar they received. No data is collected or transmitted when doing so.

8. Your rights

As we receive no data from Türchenzauber, you can change or delete your content in the app at any time. You also have the rights of access, rectification, erasure, restriction, data portability and objection (Art. 15–21 GDPR). Just send us an email. You may also lodge a complaint with a data protection supervisory authority.
