Everything about payments lives in the billing portal of our payment provider: invoices, payment method, cancellation and refunds. Open it from the extension: Account & plan → avatar menu → Contact support. The same menu holds Manage billing for changing or cancelling a plan.
If you bought Pro before signing in, sign in with the same email address you used at checkout - the purchase is attached to it and will be picked up automatically.
Payment confirmation reaches us through the provider and can take up to a minute. The extension picks it up on its own; there is no need to pay again. If Pro is still missing after a few minutes, open Account & plan - it shows the current state and, if our servers are unreachable from your network, says so directly.
Notes always work offline: they are stored in your browser and never require a network. If the account screen reports that our servers are unreachable from your network or region, notes and every free feature keep working; sign-in and plan changes resume once access is restored.
Write to us through the billing portal (it is open to everyone with an account) or leave a note in the uninstall feedback form. Please include: what you did, what you expected, and what happened instead. Do not paste note contents you would rather keep private - we do not need them to reproduce a bug.
What we store and what we deliberately do not is written out in the Privacy Policy. Deleting your account, disconnecting Google Drive and turning off anonymous usage counts are all described there under "Your Choices and Data Controls".
