How Tether handles your data
The short version: we sell subscriptions, not you.
Your address book is not readable by anyone else. Not other users, and not routinely by anyone at Tether.
Nobody can look you up. There is no people search: nobody can browse or search for you, and people find you only if they already have your number or email address. To suggest connections, we match the phone numbers saved in people's address books — and a suggestion never connects anyone until one person asks and the other accepts. We keep your own number and email on your account to text you a sign-in code and send account notices.
Encrypted in transit and at rest. TLS in flight, AES-256 at rest. Photos have their location metadata stripped on upload.
Nothing is stored that you did not pick. Only the contacts you choose are saved. The rest of your address book is never uploaded.
Revoking actually revokes. Your device does not keep a copy of the fields someone shares with you — it reads theirs each time. So when they stop sharing something, it is gone, and no stale copy can hide that.
Availability shares busy and free times, nothing else. Your calendar is read on your phone, and only busy and free times leave it — never event titles, never locations.
You can leave with everything. Export as CSV, JSON, or vCard. Delete your account and, after a 30-day window to change your mind, the data goes with it.How account deletion works.
No ads, no ad-tech trackers, no data sale. Wherever you live, you can access, correct, export, or delete your data, and the Privacy Policy explains the extra rights your state's privacy law may give you.
