Subprocessors
Last updated October 20, 2026
These are the companies that process data so Caute can run. Each does so only to provide its service to Axionary Labs, under an agreement that limits it to that. None may use what you save for its own purposes.
If you add your own AI key on Pro+ or Team (Google, Anthropic or OpenAI), that company is not our subprocessor: Ask and briefs reach it under your own agreement with it, which you chose. The same goes for the assistants and apps you connect, such as Claude or ChatGPT, which read only what you let them, and for your team’s own Google Workspace or Microsoft Entra sign-in. Text is indexed and recordings are transcribed on Caute’s own servers, by models that send nothing elsewhere.
| Company | What it does | What it handles | Where |
|---|---|---|---|
| Fly.io | Runs Caute’s servers, including the sandboxes that open files. | Everything Caute processes, while it is processed | United States |
| Crunchy Data | Hosts the database, on Amazon Web Services. | Account details, the text and indexes Caute searches, notes, tags and links | United States |
| Cloudflare | Stores files (R2), runs the domain names, and receives email sent to your Caute address. | Encrypted files; email sent to your Caute address, passed straight to Caute | United States and Cloudflare’s network |
| Amazon Web Services | Holds the keys that protect each space’s encryption keys (KMS). | Encryption keys only, never content | United States |
| Provides the language model (Gemini) for summaries, titles, picture descriptions, reading hard-to-read scans, answers in Ask, briefs and proposed tag names, and for the receipt reader and deadline finder when you connect them. Never for a space kept away from AI. | The text or picture each of those needs, never used to train models | United States | |
| Resend | Sends Caute’s emails, such as sign-in links. | Your email address and the message | United States |
| Stripe | Processes payments. | Billing details; Caute never sees your card number | United States |
| Sentry | Receives reports when something in Caute breaks. | Where in Caute’s code it happened, never what you saved | United States |
We’ll update this page at least 30 days before adding a company that handles what you save, as our data processing addendum says. Questions: privacy@axionarylabs.com.
