Everything you want to know about Zelko apps.
Yes. All apps are free to download and use. Some offer optional Pro features (€0.99/month or €7.99/year) that you can unlock if you want, but the basic features are complete and unlimited.
Absolutely. All data stays on your device. We have no servers, we collect no analytics, we don't even know who uses our apps. Google Drive backup is optional and goes to your personal account.
Yes, 100%. All Zelko apps work completely offline. The only exception is Zelko Health which can search food items online via Open Food Facts, but this function also caches results for offline use.
No. Open the app and start using it immediately. We don't ask for name, email or phone number. The only optional account is Google for Drive backup.
Yes, but it's completely local and optional. You can add a name and avatar that appear in the app — no registration, no email, no password. Profile data stays on your device. If you change phones, use Google Drive backup to retrieve it. It's not an account in the traditional sense: it's just a local customisation that makes the app yours.
You can export data in local JSON format or, optionally, back up to your personal Google Drive. Backups in Drive are in the app's private folder and are not accessible to our team.
Yes, at any time. From Settings → Data → Delete all data. Or simply uninstall the app: Android automatically deletes all local data.
Our path towards a European, independent digital ecosystem that respects your freedom.
Zelko ID and Zelko Drive will use servers located in Europe. European users' data will remain in Europe, under GDPR jurisdiction.
We only collect what is needed to make the app work. No trackers. No data sold.
Profile, cloud, drive — all are and will always be optional. No feature will be tied to creating an account. The choice is yours alone.
Every decision, every change is communicated openly. No silent policy updates, no surprises. What you see is what you get.
