Mint Affiliatesby Mint Labs

Security policy

Last updated September 29, 2026

This policy describes how Mint Labs protects the data Mint Affiliates handles, including shoppers' personal data 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. We store no shopper names, emails, phone numbers, addresses or customer ids; referred orders are stored as order number and amounts only. Affiliates' details are removed when the merchant deletes the affiliate.
  • Affiliate sign-in uses single-use links (15-minute expiry by email, 72 hours when sent by the merchant) and HttpOnly, Secure, SameSite cookies. Only one-way hashes of links and sessions are stored. The sign-in form responds the same way whether or not an email has an account, and is rate-limited.
  • Our database is Cloudflare D1: encrypted at rest, with automatic 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 shopper data.
  • Webhooks and storefront (app proxy) requests are verified with Shopify HMAC signatures; unsigned requests are rejected.
  • Commission records are processed idempotently: each order and refund is recorded once even if Shopify delivers it more than once.

Access control

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

Passwords and authentication

  • Every account with access to production (hosting, Shopify Partner and email) 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. Logs never contain shoppers' or affiliates' email addresses or other personal data values.
  • 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.
