Security policy

Last updated September 29, 2026

This policy describes how Mint Labs protects the data Mint Tracking handles, including personal data of merchants' customers processed on behalf of merchants. It applies to everyone at Mint Labs with access to our systems.

Data loss prevention

• We keep as little data as possible. Orders are read from Shopify when a shopper looks one up and are not stored. The email address a shopper types is only compared with the order's email address in memory; it is never written to our database or logs.
• The dashboard keeps shipment status, dates and carrier names keyed by Shopify IDs and order numbers, deleted 75 days after shipping. No names, email addresses, phone numbers, addresses or tracking numbers are stored.
• Order lookups need both the order number and the checkout email address. Unknown orders and wrong email addresses get the same answer, and repeated failures are blocked per order number, per visitor (keyed one-way hash of the IP address, kept for an hour) and per store.
• Our database is Cloudflare D1: encrypted at rest, with point-in-time recovery so it can be restored to any minute in the retention window.
• All traffic uses HTTPS (TLS). Production and development use separate databases; development never uses real merchant or customer data.
• Webhooks and storefront requests are verified with Shopify HMAC signatures; unsigned or stale requests are rejected.

Access control

• Only authorised Mint Labs personnel who need it to run and support the app can access production systems.
• The app has no internal screen that lets us browse orders or customers' personal data.
• Access is removed immediately when it is no longer needed.

Passwords and authentication

• Every account with access to production (hosting and Shopify Partner) uses a strong, unique password stored in a password manager.
• Two-factor authentication is required on all of those accounts.
• API secrets are stored as encrypted environment secrets, never in source code, and are rotated after any suspected exposure.

Logging

• Every request to the app, including requests that process personal data, is logged with a timestamp by our hosting provider's request logs. Our own log lines never contain customers' names, email addresses, addresses or order details.
• Logs are reviewed when investigating errors or suspected incidents.

Security incident response

1. Report. Anyone can report a suspected issue to support@stickermint.com. We acknowledge reports within one business day.
2. Contain. We stop the exposure first: disable the affected feature, revoke and rotate keys and access tokens, and block abusive traffic.
3. Investigate. We use request logs and database history to find what happened, which shops and data were affected, and when.
4. Notify. If personal data was affected, we notify affected merchants without undue delay and within 72 hours of confirming the incident, and tell Shopify where required, with what happened and what we are doing about it.
5. Recover. We fix the root cause and, if needed, restore data from point-in-time recovery.
6. Review. We record each incident and the lessons learned, and update this policy.
