Privacy Policy
1. What we collect
Device identifier: a random ID generated in your phone's Keychain on first launch. It is not linked to your name, phone number or Apple ID.
Push token and language: the token Apple assigns for notifications and your chosen language, used to send new-coin report alerts.
Subscription receipts: Apple-signed transaction details (product, transaction ID, expiry), used to confirm your subscription. We never see your payment card or Apple ID.
Abuse protection: the server counts requests per minute. IP addresses are stored only as an irreversible hash, for no more than 1 day.
2. What we don't collect
We do not collect your name, email, contacts, location, advertising identifier or photo library. The app only writes a report image to Photos when you tap "Save", and never reads your library. The app contains no third-party analytics or advertising SDKs.
3. How we use it
Only to deliver research reports, new-coin notifications and subscriptions. We do not sell your information or use it for advertising.
4. Service providers
Apple (App Store payments and push notifications) and Cloudflare (server and data hosting), each under its own privacy policy.
5. Retention
Device identifier, push token and language are kept for 180 days after you last use the app. Subscription records are kept for 180 days after the subscription ends. Push delivery logs are kept for 180 days. After that they are deleted automatically.
6. Your choices
You can turn off notifications in Settings at any time, and deleting the app stops all collection. To ask for earlier deletion of server-side data, or for any privacy question, email support@coincatcher.app. We reply within 15 business days.
7. Children
The app is intended for users aged 18 and over and is not directed at minors.
8. Changes
When this policy changes, we will post the new version on this page and update the date.
