Questions, bugs or feedback about Math Puzzles, Examen Civique or GridPop — we usually reply within 24 hours.
Each app has a dedicated support email, store page and version notes.
If your question isn't covered here, just email us — we read every message.
Email contact@z2pdevops.com with a short description of what you were doing, your device model, and your iOS version (Settings → General → About). Screenshots or a screen recording help a lot. We usually reply within 24 hours.
Yes. Math Puzzles, Examen Civique and GridPop all run fully offline once installed. No account, no sign-in, no internet connection required after the initial download.
No. The apps don't ask for your name, email or any personal information. Game progress and preferences are stored locally on your device only — they never leave it. No analytics, no tracking, no ads.
Because we don't use accounts, progress is stored locally on each device. If you re-install the app on the same device and used iCloud Backup for that app, iOS will restore your data automatically. Moving to a brand-new device requires starting fresh.
Refunds for App Store purchases are handled by Apple. Visit reportaproblem.apple.com, sign in with your Apple ID, find the purchase, and request a refund. If you'd like us to know why, drop us a note — feedback helps us improve.
Absolutely — feedback shapes what we build next. Email contact@z2pdevops.com with your idea. Math puzzle suggestions and Examen Civique question corrections are especially welcome.
Our iOS apps require iOS 15 or later and run on iPhone and iPad. On Android they support Android 8.0 or later. We test against the two most recent major OS versions on supported devices.
No accounts, no third-party trackers, no ads. App progress and settings are stored locally on your iPhone or iPad and never sent to a server. The full privacy policy is linked in the footer.
Email us directly. Tell us which app, your device and iOS version, and what's happening — we'll get back to you fast.
