Lupe: privacy policy
Last updated 2 November 2026
Lupe is a personal app built and used by one person, James Gibbel. It is not offered to the public and has no other users. This page describes what it does with Google account data.
What it reads
Lupe uses read-only access to one Gmail account (the developer's own) to find automated transaction-notification emails, and to one Google Calendar account (the developer's own) to show a schedule.
What it does with it
Details extracted from those emails and events are stored privately by the developer, on hardware the developer controls. They are used only to show the developer their own spending and schedule. The data is not sent to any third party, not used for advertising, and not sold.
Who can see it
Only the developer. No one else has access to the app or its data.
Keeping and deleting
The data stays until the developer deletes it. Access can be revoked at any time at myaccount.google.com/permissions, which stops Lupe from reading anything further.
Google API Services
Lupe's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
