Field Clock ("the app") is developed by Sightline Technologies ("we," "us," "our"). This policy
explains what data the app collects, how it's used, and your choices.
Data we collect
Precise location. Field Clock uses your device's precise (GPS) location to
detect when you arrive at and depart from locations you've saved in the app. This requires
checking your location periodically while the app is running in the background, not just while
it's open on screen. Location is checked on the interval you choose in Settings (5, 10, or 15
minutes).
Email address. If you create an account (required for Field Clock Plus), we
collect your email address to authenticate you and to deliver the optional weekly summary email
described below. If you use the free tier without an account, no email address is collected
unless you choose to include one when submitting feedback.
Visit records. The app records the arrival and departure time for each visit to
a saved location, along with the location's name. For free-tier use this stays on your device
only. For Field Clock Plus accounts, this data is also stored in our cloud database so it syncs
across devices and survives a reinstall.
How we use this data
- Precise location is used solely to detect arrivals and departures at your saved locations
(geofencing). It is not used for advertising, analytics, or any purpose unrelated to this
core feature.
- Email address is used for account login and, if you enable it, to send you a weekly summary
email of your visits over the previous 7 days. This feature is opt-in and can be turned off
at any time in Settings.
- Visit records are used to display your visit history in the app and, for Plus subscribers,
to generate the weekly summary email.
Data sharing
We do not sell your data or share it with third parties for advertising or marketing.
Data is processed by service providers acting on our behalf, solely to operate the app:
- Supabase hosts our backend database and authentication for Field Clock
Plus accounts.
- Our email delivery provider (SMTP) is used only to send you the weekly summary email you
requested, and to deliver feedback replies. It is not used for marketing.
These providers only process data to provide the service to you and are not permitted to use it
for their own purposes.
Data retention and deletion
You can delete your data at any time from Settings:
- Delete all data permanently erases your saved locations and visit history
and resets your settings.
- Delete account permanently deletes your account and all associated data,
including saved locations, visit history, and settings.
Deleted data is not recoverable.
Data security
Data is encrypted in transit between the app and our backend (HTTPS) and between our backend and
our email provider (TLS).
Children's privacy
Field Clock is not directed at children and we do not knowingly collect data from children under
13.
