CounterpartPrivacy policy
Last updated: November 9, 2026
Counterpart is a safety-alert service for small shops, operated by Stacktech ("we", "us"). This policy explains what we collect, why, and who sees it.
What we collect
- Account details: your name, and your Apple ID sign-in identifier (we do not receive your Apple password).
- Shop details: your shop's name and address, and the names and roles of the people you invite to your shop's team.
- Phone numbers: mobile numbers you or your team give us so we can send text messages (see below).
- Alert records: when an alert was sent, from which device and control, who received it, when it was delivered and acknowledged, and whether it was a test. Records are kept so a shop has a trustworthy history.
- Device information: push notification tokens, a device name you choose, and the device model, needed to deliver alerts.
What we do not do
- We do not sell your information or share it for advertising.
- We do not track your location. The app does not ask for it.
- We do not share phone numbers with third parties for marketing, and we do not use them for anything except the messages described here.
How we use it
Only to run the service: to deliver alerts and reminders to the people you chose, to show who has acknowledged, to keep an alert history for your shop, and to keep the service secure and working.
Who processes it for us
- Supabase: hosts our database and server functions.
- Apple: sign-in and push notifications.
- Twilio: sends text messages and, in a later release, phone calls.
- Microsoft Azure: hosts this website.
These providers process data on our behalf and only to provide their service.
Text messages
Mobile numbers and text message opt-in information are never shared with third parties or affiliates for marketing or promotional purposes. See Text messages for how people opt in and out.
Retention and deletion
Alert history is kept for as long as your shop uses Counterpart, so you have a record if you need one. To remove your account, a person, or your shop's data, email support@counter-part.app and we will act on it promptly.
Security
Data is encrypted in transit, access is limited by shop membership, and our service credentials are kept out of the apps.
Children
Counterpart is for business use by adults and is not directed at children.
Changes and contact
If this policy changes we will update the date above. Questions: support@counter-part.app.
