Every vendor who touches your data. Listed.
We use as few vendors as we can, and list each one before it processes anything. Each entry below is bound by a written GDPR Art. 28 data processing agreement with a valid transfer mechanism and processes only the data its service needs. Purchases go through Avonao Billing (with Stripe as merchant of record) and sign-in through Avonao ID, both operated by Avonao, Inc. and listed on the Legal page. Customers are notified at least 30 days in advance of any addition; objections accepted via privacy@agined.com.
Sub-processors.
These are the vendors the service calls today, taken from the code. Rows marked “When configured” send nothing until that vendor is switched on. The same list is published at /.well-known/sub-processors.json.
