Service providers
Roles of services supporting the website and product features.
On this page
Public website
Cloudflare delivers and protects vintolk.com. Technical connection information may pass through it when you visit pages. Reading product information does not require product servers or sign-in services.
Product sign-in and email
For products using the disclosed shared sign-in configuration, Google confirms the Google account and Supabase Auth supports app identity and sessions. Account email through Resend applies only to enabled email features. Active service details and product notices identify information, purpose and scope; the information website does not create sessions with these services.
Website contact email (when configured)
The optional contact form on this information website uses a Cloudflare Pages Function for validation and rate controls, then Resend to deliver mail to [email protected]. This path is separate from product account email. It is active only when Pages secrets (including a verified CONTACT_MAIL_FROM sender) and CONTACT_ALLOWED_ORIGINS are configured. Until then, treat online form delivery as not enabled and use the published mailbox directly. Abuse controls include Cloudflare Turnstile Siteverify (required) and best-effort Cache throttling (not a hard atomic quota). Required secrets include RESEND_API_KEY, verified CONTACT_MAIL_FROM, CONTACT_ALLOWED_ORIGINS, and TURNSTILE_SECRET_KEY, plus a public Turnstile site key for the widget.
Infrastructure and AI by feature
Calling, online storage, project execution and AI infrastructure belong to the product you use and do not start from viewing the homepage. Before sending content to AI, the feature must identify the sending action and relevant service. New providers or processing regions must be reflected in appropriate notices before use.
Limits and questions
Providers are used for relevant purposes under applicable conditions; listing a provider does not endorse every service it offers. Send account or product data questions to [email protected]. The active list is maintained when actual services change.
