SG Twin  /  Privacy

Privacy is the product

Your afterlife, your rules.

A digital self is the most personal thing a person could ever create. SG Twin is built the only way that's acceptable — private by default, owned entirely by you, and impossible for us to read.

Owner-only keys

Your vault is encrypted with AES-256-GCM. We hold the encrypted data; only you hold the key. We literally cannot read your life.

AES-256-GCM · keys never leave you

Consent by design

Nothing is captured without your say-so. Pause capture, exclude a person or a place, or delete a moment — any time you choose.

pause · exclude · delete — anytime

Never for sale

Your memories are not training data for anyone else. Never sold, never shared, never advertised against. Ever.

no ads · no resale · no third parties

Legacy access controls

Name who inherits access, set waiting periods before it unlocks, and revoke at will while you're here.

heirs · timing · revocable

Leaves with you

Export or erase your entire twin in a single action. It is yours, completely — to keep, to move, or to end.

full export · full erase · one action

Processed close to you

The model that understands you is trained on dedicated hardware, not scattered across faceless clouds — private by architecture, not just by policy.

on-device understanding

Why we can't read your life — even if we wanted to

Most services promise privacy in their terms. We designed it into the maths. Your vault is sealed with a key derived for you and held by you; what reaches our storage is ciphertext. There is no master key, no back door, and no internal tool that turns your memories back into words. Privacy that depends on our good behaviour isn't privacy — so we removed ourselves from the equation.

If we can't read it, we can't lose it, leak it, or sell it.

Your rights, always

  • Consent — capture only ever runs with your permission, and you can pause it in a tap.
  • Access — see what your twin has learned, and review every transcript before it's kept.
  • Correction — edit or remove anything that doesn't reflect who you are.
  • Portability — export your entire twin whenever you want.
  • Erasure — delete everything, permanently, in one action.
  • Inheritance — decide exactly who may ever access your twin, and revoke it while you're here.
