Privacy Policy — Cryptogram Daily

Last updated: 14 June 2026

Cryptogram Daily ("the app", "we", "us") is published by BTH. This policy explains how the app handles your data. In short: the app is built to work offline and collects no personal data itself. The only information that leaves your device relates to optional in-app purchases, which are handled by our payment providers.

Information we do not collect

• We do not collect your name, email address, contacts, photos, or location.
• The app contains no ads and uses no advertising networks.
• We do not use third-party analytics, tracking, or advertising identifiers.
• No account, sign-in, or registration is required to use the app.

Information stored only on your device

Your puzzle progress and decoded quotes, daily streak, statistics, hints, and settings are stored locally on your device. This data never leaves your device, is not transmitted to us, and is permanently removed when you uninstall the app.

Purchases

If you buy a subscription or the lifetime upgrade, the payment is processed by the Apple App Store or Google Play, and entitlements are managed through our purchases provider, RevenueCat, Inc. To enable and restore purchases, RevenueCat processes:

• an anonymous app-user identifier generated on your device;
• purchase and transaction details and your subscription status;
• basic device and platform information needed to validate the purchase.

This information is used solely to deliver and restore your purchases and premium access. It is never used for advertising. RevenueCat acts as our data processor — see RevenueCat's Privacy Policy. Your actual payment details (card, billing information) are handled entirely by Apple or Google; we never see or store them.

Notifications

The app can show an optional local daily reminder. These notifications are scheduled on your device only. No notification server is used and no data is sent to us.

Children

The app is intended for a general, adult audience and is not directed at children under 13.

Your rights

Because your puzzle data is stored only on your device, you can erase it at any time by deleting the app. For purchase-related data held by RevenueCat, you may request access or deletion by contacting us. Depending on where you live (for example, the EEA/UK under the GDPR, or California under the CCPA), you may have rights to access, correct, or delete your personal data.

Changes to this policy

We may update this policy from time to time. The "last updated" date above will reflect any changes.
