Write to [email protected]. Bug reports, questions, refund questions, feature requests and privacy requests all go to the same place. Replies usually come within two working days.

What to include

• Which app or extension, and its version if you can find it
• Your device and operating system version, or the browser for an extension
• What you expected to happen and what happened instead
• A screenshot, if the problem is something you can see

You never need to send passwords, payment details or personal documents. We will not ask for them.

Product pages

• BookGap — Chrome extension for Amazon book research
• The Android habit tracker is still in development; its page will appear here when it ships.

Privacy requests

To ask what data is held about you, or to have it deleted, write to the same address. See the privacy page for what is collected in the first place, which for most of these products is nothing.
