Pigpen Code - Pigpen Cipher. Privacy Policy. Effective 6 November 2026. Developer: Artificial Apps & Games. Contact: artificialappsandgames@gmail.com. Messages and symbols are processed locally on your device. We do not collect or transmit messages; no account is required. Learning progress, XP, answer counts, streak, practice date, appearance, sound and optional rating remain on your device. Messages are not saved in a message database. This version shows ads from Google AdMob. AdMob may use your device advertising ID and information about ad views and taps to serve, personalise and measure ads, and to prevent fraud. A banner ad appears at the bottom of each screen, and an interstitial ad may appear only after every third completed training session, and only when one is already loaded. Depending on your region, you will be asked for consent before personalised ads are shown. You can reset or delete your advertising ID in Android Settings > Privacy > Ads. Your messages, learning progress, XP, streak and settings stay on your device and are not sent to us or to any advertising partner. This version contains no analytics or sign-in SDK. Copy, PNG/SVG exports and sharing happen only at your request. Destination apps and storage providers have their own privacy policies. Confirmed progress reset clears learning metrics and preserves preferences. Clearing app data or uninstalling removes local data. No cloud account backup is provided. Pigpen is an educational puzzle cipher, not secure encryption. The app has no social accounts and does not collect personal information from children. Google Sites hosts this policy and may process technical website requests under Google privacy policies, separately from local app processing. We may update this policy when the app changes.
