Privacy

We only collect what is needed to confirm one person signed once.

We do not sell personal data.

We do not publish exact locations.

Public maps and statistics use approximate and aggregated data. Country is the smallest unit shown publicly.

People can request deletion of their signatory record.

Signing this letter does not create a financial account, token account, or investment product. There is no payment, no balance, and no transferable asset.

What we store

• A hash of your authentication provider’s user id, so we can recognise a returning signer without storing the underlying account.
• If you sign with email, a hash of your email address — not the address itself in plain form.
• An optional display name only if you choose to make it public.
• An approximate country, region, and (optionally) city, derived from your IP at the moment you sign. We do not store precise coordinates.
• The timestamp at which you signed.
