Your prompts and responses never reach us. The Contextify proxy runs on your own machine. Prompts, completions and your Anthropic API key stay on that machine and go directly to Anthropic. We receive counters — how much was saved, how many requests — never content.
| Data | Why |
|---|---|
| Email address | To identify your account, send verification and password-reset links, and contact you about your account. |
| Password (hashed) | Stored only as a scrypt hash. We cannot read your password and cannot recover it for you. |
| IP address at sign-up, and during sign-in attempts | Rate limiting and abuse prevention. Not used for tracking or profiling. |
| Machine identifier and a hardware fingerprint | A hashed value that lets us apply the free allowance once per machine. We cannot reverse it to your hardware. |
| Usage counters | Savings in USD, request counts and token counts, so your balance is accurate. |
| Payment details | Handled entirely by our payment processor. We never see or store your card number. |
The proxy can report aggregate counters — uptime, requests handled,
tokens saved, dollars saved — identified only by a random installation
ID. It contains nothing about you, your prompts, or your machine. Turn it
off at any time by setting TELEMETRY_ENABLED=false.
We do not sell your data and we do not share it for advertising. We use a small number of processors purely to run the service: an email provider to deliver verification and reset messages, and a payment processor to handle billing. They receive only what their job requires.
We may disclose information if legally required to, or where necessary to investigate abuse of the service.
Account data is kept while your account exists. Sessions expire after 30 days. Verification links expire after 24 hours and password-reset links after one hour. Records of machine allowance are retained after an account closes, because they are what stops the free allowance being claimed repeatedly — they contain no personal information.
You can ask us for a copy of your data, ask for it to be corrected, or ask for your account and its data to be deleted. Email enterprise@contextifyai.com and we will respond within 30 days. Depending on where you live you may have additional rights under the GDPR or CCPA; we apply the same process to everyone.
Passwords are hashed with scrypt. Session and machine tokens are stored only as SHA-256 digests, so a copy of our database yields nothing that can be presented as a credential. All traffic to the service is encrypted in transit. No system is perfectly secure, and we will notify affected users promptly if a breach affects their data.
If we change this policy materially we will update the date above and, for significant changes, notify account holders by email.
