Security & your data
How Landmark protects the way you sign in, and the data it does. And does not. Collect. The short version: strong, phishing-resistant sign-in you control, and first-party data you consented to, nothing hidden.
How you sign in
Set a password, add passkeys for phishing-resistant sign-in that never leaves your device, and register a recovery phone so a lost device can't lock you out. Password and email changes require your current password and fire an email plus an in-app alert, so an unauthorized change is loud rather than silent.
Sign out everywhere
If you sign in on a shared or lost computer, open the Security page and use Sign out all other devices. It ends every session except the one you're on, immediately. The fastest way to boot a lingering login without changing your password. The Recent sign-ins card lists the devices with a login, and a sign-in from somewhere new triggers an alert.
What data we collect
Landmark works with first-party data you gave us or connected: your account details, the platforms you link, and the events those platforms send. When a feature needs a new permission, it asks first and tells you why. We do not buy audience data, and we do not infer sensitive attributes about your viewers.
- First-party and consented
- Only data you provided or explicitly connected. Nothing acquired behind your back.
- No covert fingerprinting
- We don't build hidden device fingerprints to track people across the web. Basic abuse signals are used only to keep sign-up fair, never to profile viewers.
- Payment data stays with Stripe
- Card details are handled entirely by Stripe. Landmark never sees or stores a card number. See Where your money is held.
Good habits
- Use a password manager
- Unique passwords everywhere, so one leak can't cascade.
- Prefer passkeys over SMS
- A phone number can be lost or SIM-swapped; a passkey can't.
- Keep recovery current
- Your recovery email and phone are how you get back in if you're locked out.
