Frequently asked questions
Is Metrics free?
Yes. Everything on this page is free.
Does it work offline?
After the first online sign-in, captures are saved on your device and synchronize automatically when you are back online.
Can I fix a wrong entry?
Yes. Edit a value or its timestamp directly, or delete the entry — with a short undo window after deletion.
Can I export my data?
Each metric downloads as a CSV file, and your account can export a full JSON backup of every metric and entry.
Who can see my numbers?
Only you. Sensitive metrics can be moved into a private section behind a device code, and deleting your account removes all data.
