Contact
A dedicated public support mailbox is not currently configured in the app repository, so this site does not invent or publish a placeholder address.
For direct developer support, use the developer contact/support link associated with Tape Measurement on its App Store product page. When reporting an issue, include the app version, iOS version, device model and a short description of what happened. Do not send passwords, payment-card data, Apple Account credentials or other secrets.
Privacy questions
Use the same verified developer contact route and mention that your question concerns the privacy policy.
App Store release action
Before public release, the developer should add a dedicated public support email or equivalent verified contact method here and in App Store Connect.
