Privacy Policy

The short version

What we collect

How translation works (and where your voice goes)

During a call, speech is streamed to Google's Gemini API, which returns the transcription and translation; the optional spoken interpreter voice is generated by Microsoft's speech service. These providers process your family's audio and text solely to provide the translation for your call — under our agreements they do not use it to train their models. Because translation happens on servers, calls are encrypted in transit (not end-to-end encrypted — no live-translation service can be). No one at Grandkins — and no contractor — listens to or reads your family's conversations; the only exceptions are content you share with us yourself when asking for help, or when the law requires it.

What we never do

Who we share data with

Only service providers that Grandkins needs to run, processing on our instructions: Amazon Web Services (hosting, USA), Google (translation), Microsoft (interpreter voice), Stripe (payments), Resend (transactional email), and Meta WhatsApp / Twilio (delivering the invite and notification messages you ask us to send). We may also disclose data if the law requires it. There are no other recipients.

Children

Children under 13 are added only by a parent or legal guardian with a fresh password confirmation and explicit consent (COPPA). What we collect from a child is the same as any member: name, language, and the call content described above. Children never have their own credentials, and the parent can review or permanently delete a child's information at any time in Settings.

Retention and deletion

Your rights

Security

TLS everywhere, hashed passwords (scrypt), one-time expiring join links (stored only as hashes), consent-gated archive features enforced server-side, per-family data isolation, and nightly encrypted backups. Data is hosted in the United States.

Changes to this policy

If we change this policy we will update the date above and, for material changes, tell you in the app or by email. We will not reduce your rights under this policy without your explicit consent.
