Signelle is a private personal planning application built and operated by a single individual for their own exclusive use. It has no other users, no sign-up, and no public availability.
Signelle is operated by an individual, reachable at leekatrinat@gmail.com. All questions about this policy should go to that address.
Signelle accesses data from Google accounts owned by its sole operator, using the following read-only scopes:
gmail.readonly — reads email messages and metadata in order to surface important messages and extract scheduling and financial information.calendar.readonly — reads calendar events in order to display and plan around an existing schedule.These scopes are read-only. Signelle cannot send, modify, or delete email, and cannot create or alter calendar events.
Data is used solely to display and organize the operator's own information within the application: to build a daily task list, show an existing schedule, flag messages needing attention, and produce personal summaries. It is not used for any other purpose.
Data is stored in a private database instance accessible only to the operator, encrypted at rest, and protected behind authentication. OAuth credentials are stored encrypted and are never included in application source code.
Data is not shared. Signelle does not sell, rent, transfer, or disclose data to any third party. There are no advertisers, analytics vendors, data brokers, or partners. No human other than the operator has access.
Signelle's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google user data is not used to develop, improve, or train generalized artificial intelligence or machine learning models.
Data is retained only while it remains useful to the operator and may be deleted at any time. Access can be revoked at any point at myaccount.google.com/permissions, which immediately ends Signelle's ability to read any further data.
This policy may be updated as the application changes. The revision date above will be updated accordingly.
