Anthropic's API training default

Anthropic's Commercial Services Agreement is explicit: customer content from commercial products is not used to train Anthropic models. That covers the Anthropic API, Claude for Work, and Claude Gov. The Consumer Terms that govern free Claude.ai conversations are separate, and the privacy posture there is different.

When Meetily users select Claude as their summary provider via BYOK, the request hits api.anthropic.com under your API key and your workspace's contract. The defaults on this page apply unless you have a separate commercial arrangement that overrides them.

Retention

For commercial API traffic, Anthropic's published commercial data retention policy is that it automatically deletes inputs and outputs on its backend within 30 days of receipt or generation. Conversation content (your prompts and Claude's outputs) is not retained by default beyond that window, and Anthropic states it designs each feature for the smallest possible retention footprint. Longer retention applies only where you opt into a stateful feature, where you submit feedback (thumbs up or down, retained up to 5 years per Anthropic's privacy article), or where retention is required by law or to enforce the Usage Policy.

If a chat or session is flagged for a Usage Policy violation, Anthropic may retain inputs and outputs for up to 2 years and trust-and-safety classification scores for up to 7 years. Meetily's default integration sends no feedback and only the prompt and response, so the 30-day default is the relevant window for typical Meetily traffic. For exact, contract-specific windows, the authoritative source is the current Anthropic Data Processing Addendum referenced from the Commercial Terms; reviewing it before deployment is recommended for any regulated workload.

Zero data retention

Anthropic offers zero data retention for eligible customers through a commercial agreement. Under ZDR, customer data is not stored at rest after the API response is returned, except where needed to comply with law or combat misuse. ZDR applies to the Claude Messages and Token Counting APIs (the path Meetily uses), but it does not cover stateful features such as Batch processing, the Files API, or Managed Agents, nor the Console or Workbench interfaces. To enable it, contact Anthropic sales; it is enabled per organization and is not a self-serve toggle in the public dashboard.

Note that Anthropic's designated Covered Models (currently Claude Fable 5 and Claude Mythos 5) require 30-day data retention and are not available under ZDR; requests to them from a ZDR-only workspace return a 400 error. Organizations with ZDR can opt specific workspaces into 30-day retention to use those models while keeping ZDR elsewhere. For workloads handling protected health information, Anthropic now offers HIPAA-ready API access under a BAA as an alternative to ZDR.

How Meetily uses Anthropic

Meetily routes Anthropic traffic through your own API key. Your workspace's contract terms apply. The transcript text is sent over TLS to api.anthropic.com for summarization, and the response is returned to Meetily and stored locally on your device. Audio is never transmitted to Anthropic at any point.

If you want stronger guarantees than the cloud-default offers, switch your summary model to a local provider (Ollama). Meetily's transcription path is already local, so the local-summary path keeps the entire pipeline on-device.

Frequently asked questions

Does Anthropic train Claude models on my API prompts and outputs?
No, not by default. Anthropic's Commercial Services Agreement states that Anthropic will not train models on customer content from commercial products like the Anthropic API, Claude for Work, and Claude Gov. Consumer Claude.ai conversations are governed by different consumer-facing terms; this page covers the API path.
How long does Anthropic retain my API prompts and outputs?
Anthropic's commercial data retention policy states it automatically deletes API inputs and outputs on its backend within 30 days of receipt or generation, unless you have a zero-data-retention arrangement, you opt into a feature with longer retention, or longer retention is required by law or to enforce the Usage Policy. If a chat or session is flagged for a Usage Policy violation, Anthropic may retain inputs and outputs for up to 2 years and trust-and-safety classification scores for up to 7 years. Feedback you explicitly submit (thumbs up or down) is retained for up to 5 years; Meetily's default integration sends no feedback, only the prompt and response.
Is zero data retention available for the Anthropic API?
Yes, for eligible customers via a commercial agreement. Under a ZDR arrangement, customer data is not stored at rest after the API response is returned, except where needed to comply with law or combat misuse. ZDR applies to the Claude Messages and Token Counting APIs (the path Meetily uses), but not to stateful features like Batch, Files, or Managed Agents. ZDR is enabled per organization; contact Anthropic sales to request it. Note that Anthropic's designated Covered Models (currently Claude Fable 5 and Claude Mythos 5) require 30-day retention and are not available under ZDR.
Where is Anthropic API data stored geographically?
Anthropic processes API traffic primarily on US infrastructure. Regional residency commitments depend on your contract; check the DPA and your account configuration.
How do I request deletion of data Anthropic has retained?
Submit a deletion request through Anthropic's Trust Center or contact support per the process described in your Commercial Terms. For consumer Claude.ai data, use the in-app data controls.
Does Anthropic Claude have SOC 2 or HIPAA compliance?
Anthropic publishes its compliance posture on the Anthropic Trust Center at trust.anthropic.com. For HIPAA, Anthropic now offers HIPAA-ready API access under a signed Business Associate Agreement (BAA) on a HIPAA-enabled organization; this is a separate path from ZDR and no longer requires ZDR. Consult Anthropic sales for the current scope and eligible features.
How does Meetily handle Claude when I pick it as my summary provider?
Meetily transcription is always 100% local. When you select Claude as your summary provider in the BYOK flow, Meetily routes transcript text (not audio) to api.anthropic.com using your own API key. The retention and training defaults on this page apply to your traffic, not Meetily's.
What if I want zero retention but my workspace does not have ZDR enabled?
Two options: ask your Anthropic account team to enable zero data retention on your workspace, or switch your Meetily summary model to a local provider like Ollama. Meetily's transcription path is unchanged on the local-summary route, so the entire pipeline runs on your device.

Use Anthropic Claude with Meetily, on your terms

Meetily transcription stays 100% local. For summaries, bring your own Anthropic Claude key (BYOK) so the data path matches the policy you just read - or pick a local model if you want zero retention by construction.
