A bug report that we can act on
- What you were doing, step by step.
- What you expected to happen, and what happened instead.
- The time it happened, including your time zone if the bug concerns a reminder or deadline.
- Your browser and device, or whether you were on a phone.
- The exact text of any error message, if one appeared.
Please do not send
No passwords, full card numbers, or other payment credentials. You never need to send those to ask for help. If we need to check your account, we will look it up on our side rather than ask you to prove who you are with a secret.
Security reports
If you believe you have found a security problem, email the address above with Security at the start of the subject. Please describe the issue and how to reproduce it, and give us a reasonable chance to fix it before posting details publicly. We will not pursue anyone who reports a problem in good faith.
Faster answers
Many questions are already answered on the help page: where the return date comes from, when reminders are sent, how to record a refund, and how to export or delete your data. The privacy page covers what is stored.
