Privacy Policy

Summary

• No account, no login, no sign-up.
• We never see or ask for your Apple Account, email address, password or payment details.
• The app cannot read your App Store balance. You type the amount yourself.
• No ads, no tracking, no third-party analytics or advertising SDKs, and we do not sell data.

Data stored on your device

Your entered balance, purchase plan, purchase log, stamps, souvenir collection, museum progress, language and settings are stored only on your device. A random 9-digit support code is created the first time you open the app. It is not linked to your name or Apple Account.

Data we receive

To help you if a purchase goes wrong, the app sends the following to our server:

• Purchase records: your support code, the Apple transaction ID, product, price, currency, App Store country, date and app version.
• Support chat (only if you write to us): your messages, your support code, the app's language and version, the device type and iOS version, and your recent purchase records so we can find the purchase you are asking about. If you choose to attach a photo or screenshot, it is shrunk on your iPhone and stored with the chat; photos are deleted automatically after 90 days. Photos are never sent for translation.
• Apple notifications: Apple tells our server when a purchase is refunded, together with the transaction ID.
• Anonymous usage counts: when a step happens in the app (opened, balance entered, plan shown, purchase started or completed, balance at 0, support opened, share, rate, reminder set or opened), the app sends only the name of the step and your App Store country, at most once a day per step. No support code, device ID or other identifier is sent, so these counts cannot be linked to you.

Translation of support messages: so that we can answer in your language, support chat messages are translated by an AI translation service (Anthropic's Claude, through an API provider). Only the message text and the target language are sent for translation; the provider does not receive your support code.

Reminder: if you choose "Remind me tomorrow" and allow notifications, the reminder is scheduled on your device by iOS. Nothing about it is sent to us.

We do not store IP addresses with these records. Purchases are processed entirely by Apple; we never receive payment information.

How we use it

To provide customer support (finding your purchases when you contact us and answering in your language), to deliver the stamps you bought, and, through the anonymous counts only, to see where people get stuck so we can improve the app. The legal basis is the performance of our service to you.

Where and how long

Data is stored on our server in Germany (Hetzner Online GmbH, Nuremberg). Purchase records and chat messages are kept only as long as needed to provide support for your purchases. You can ask us to delete them at any time.

Your rights

You can ask to access or delete the data linked to your support code at any time by writing to us in the app (Help → Write to us). Deleting the app removes all data stored on your device.

Children

The app does not knowingly collect personal information from children and contains no account or social features.
