Security policy

Last updated October 1, 2026

This policy describes how Mint Labs protects the data Mint Swatches handles. The app works with product data and the merchant's settings; it doesn't collect or store personal data of merchants' customers. It applies to everyone at Mint Labs with access to our systems.

Data loss prevention

• We keep as little data as possible: our database holds each store's settings (option names, colours, style) and product groups (product IDs, titles and swatch labels). The app stores no customer data.
• Swatches are rendered by the store's theme from Shopify's data, and shopper interactions stay in the shopper's browser. Card-swatch lookups through the app proxy carry product handles only; the customer ID Shopify adds for logged-in shoppers is ignored and never stored or logged.
• 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 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 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

• The app logs its own errors and webhook events (store domain, event type, timestamp). Our hosting logs keep no per-request addresses or query strings, and logs never contain customers' personal data.
• 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.
