Security policy

Last updated September 29, 2026

This policy describes how Mint Labs protects the data Mint Wholesale 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. Customers are identified only by their Shopify customer ID; names and email addresses are fetched from Shopify when a merchant views them and are never written to our database or logs.
• Wholesale application answers are written only to the customer's record in the merchant's own Shopify store; our database holds just the customer ID and the application status. Pricing runs inside Shopify's checkout (Shopify Functions without network access), so cart and customer data from checkout never reaches our servers.
• 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. The application form also requires a signed-in customer, a per-customer form token and rate limits.

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

• 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 customers' names, email addresses or addresses.
• 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.
