Support OTPPhone

OTPPhone is independent and built in the open. It carries no ads, no analytics, and no trackers, and it never sells your data — because it has none to sell. The trade-off is that there is no revenue behind it.

If the app is useful to you, a donation helps cover the things that keep it running and improving:

• Relay server hosting, so messages keep flowing.
• The Google Play developer account and distribution costs.
• Time spent on security fixes, features, and audits.

Every contribution, of any size, is genuinely appreciated. There is no paywall and no premium tier — donating is entirely optional, and the app stays fully featured and free for everyone.

Crypto goes straight to a non-custodial wallet — no middleman and no fees beyond the network's own. Scan the QR or copy the address. Monero is recommended for the best privacy.
