Every keyboard app asks for your trust. Relay is built so it needs as little of it as possible: we can't read your vault, by design. Here's the architecture, in plain English.
In 2017, a popular keyboard app leaked the personal data of 31 million people from an unsecured server: names, phone numbers, locations. The lesson isn't that they were careless. It's that they had the data at all. Any promise a company makes about your data has an expiry date: a breach, an acquisition, a pivot to ads. The only privacy that survives all of those is data they never had.
Privacy isn't a policy. It's a vault that stays encrypted.
You can use Relay without signing up, so there's no profile of you to build or breach. Signing in is optional. Every permission the app uses is listed in Settings → Apps → Relay → Permissions. On iOS, the keyboard types your details with "Allow Full Access" off.
Everything you save is encrypted on your device, with face or fingerprint lock when your phone has a screen lock set. The key is generated on your phone, and we never hold it, so we can't read your vault.
On phones, the Relay keyboard won't insert into password fields. It's not a password manager, and a keyboard shouldn't be allowed near passwords. Keep Keychain or 1Password for those; Relay is for everything else people ask you for.
With a screen lock set, lock your phone and open Relay: your vault asks for your face or fingerprint. Look up the permissions in your phone's settings. Read the full privacy page. It includes a line-by-line table of what we can and can't see. The architecture does the work, not just us saying so.
