The answers, in plain words

No. TrustWords runs on iPhone and iPad with iOS 17.6 or later, and both people need it. There is no Android version for now. If your relative has an iPad, that's enough: the words show up there too.

Yes. Both people have the app, and a relationship set up between them, so they see the same words at the same time. That's what makes the words impossible to guess from outside.

Yes. The words are computed on each phone from the time: distance and time zones change nothing. You can set up the relationship remotely, with a link, and with PROTECT choose the language of each contact's words.

1. In TrustWords, tap "+" then "They are far from me".
2. The app prepares a message with a link. Send it by SMS, WhatsApp or e-mail.
3. Your relative opens the link: TrustWords installs, or opens if they already have it.
4. They accept the relationship. The shared words are computed on each side.
5. In the free mode the relationship is active after 24 h; immediately with PROTECT.

Side by side remains the simplest way: next time you meet, do the two-screens-face-to-face gesture again, and the relationship will be the same.

Yes. You choose freely which contacts you protect: two in the free mode, unlimited with PROTECT.

The caller speaks first and reads their two words. You see three words on your screen. If both words you heard are in your list, it really is them. The third word absorbs a clock difference between the two phones. The words change every ten minutes.

No. The words are computed on the phone, without any network. Only the device's time matters, and the carrier sets it automatically.

Do not continue the conversation and do not act on the request. A refused or incorrect verification is reason enough to stop, hang up and call back on the number you know. What to do, step by step.

That is exactly why verification requires no analysis: either both words are on your screen, or they are not. Nobody has to judge a voice or a story in a hurry.

No. They are generated automatically, change every ten minutes and are never reused. Someone who overheard the words of a call can do nothing with them ten minutes later.

On your phone, in the Apple keychain, encrypted. It can also be included in an iCloud backup, manual or automatic, protected by a password you choose. TrustWords has no server.

If a backup exists, you import your relationships again when reinstalling the app. Without a backup, you set the relationships up again with your relatives. With PROTECT, backup is automatic.

Yes. Your relationships come back on the new iPhone from the backup. A second device, an iPad for instance, can also serve as a backup device.

Yes, at any time in Settings. A forgotten password cannot be recovered: nobody but you knows it.

Only if you allow it, to find a name and a number when you add a contact. Nothing leaves it, nothing is sent.

French, English, German, Spanish and Italian, with common words that are easy to say on the phone. With PROTECT, each contact can have their own language.

The list of what happened in the app: relationships created, verifications done, backups. It helps you find a specific event. It does not watch your relatives and never leaves your phone.

Not if you have a backup: the app comes back exactly as it was. The activity log itself is never erased by a reset made from the app.

The app keeps working, in Essential mode: two protected contacts, a 24-hour delay for a new contact, manual backup. If you had more than two contacts, you choose which ones to keep. No data is deleted, nothing is charged.

€24.99 once, or €9.99 per year. Details are on the pricing page. Payment through Apple; the prices shown in the App Store prevail.

Filters find a specific event in the log. Statistics give an overview of your own usage, without watching anything on your relatives' side.
