Privacy policy

Your media never leaves your device

Images and videos you upload or drop in are read and displayed only in your browser. We never upload them to any server, and we don't store, view or analyse them. They are released from memory when you close the page.

What we collect when you sign in

Previewing doesn't need an account. If you choose to sign in, we collect:

• Your email address, to send sign-in codes and identify your account.
• If you use Google sign-in, the name and profile picture link Google provides, to show your account in the page header.
• Preferences you choose to save, such as your usual devices and mock content.
• Basic account records such as sign-in times, for security and troubleshooting.

How we use it

• To sign you in and keep you signed in.

We don't sell your personal information or use it for advertising.

Cookies and local storage

• A sign-in session cookie keeps you signed in and is cleared when you sign out.
• A language cookie (NEXT_LOCALE) remembers the interface language you chose.

We don't use advertising or cross-site tracking cookies.
