Privacy policy

Last updated October 8, 2026.

The short version

ReturnBy has no accounts and doesn't ask for your name or email. The calculator runs in your browser. The store, item and dates you enter are not sent to us.

Links you share

When you tap Share, the link contains the store, item type and dates you picked, so the person you send it to sees the same result. Only share it with people you're happy to show that to.

Calendar reminders

"Remind me" creates a calendar file on your device. "Add to Google Calendar" opens Google Calendar, where Google's own privacy policy applies.

Advertising and cookies

• Google's use of advertising cookies lets it and its partners serve ads to you based on your visits to ReturnBy and other sites.
