You can purchase from inside the app: Settings → About → Licence. Payment is taken through Google Play and the licence activates immediately.
If you changed device or reinstalled the app, the Restore purchase option on the same screen is all you need — you must be signed in with the same Google account.
If you installed outside Google Play (as an APK), in-app purchase is unavailable. In that case we issue you a licence key.
Write to vantis@atomicmail.io and we will send you the payment details and your key.
Paste the key into the field on
Settings → About → Licence and confirm.
Keys start with VNT.
Google's refund policy applies to Google Play purchases. For licence keys bought directly, you may request a refund within 14 days — details on the Terms of Use page.
