Privacy
Jev API is an independent prepaid API service at jev-api.com. This policy describes the personal data we collect to run accounts, billing, and the System One API. This site is not affiliated with, endorsed by, or an official product of TypeSafe.
Last updated 29 September 2026.
An account email and a hashed password. A session cookie that keeps you signed in. API keys are stored as a SHA-256 hash and a short prefix; the secret is shown once and is not kept. A usage and billing ledger records System One calls, token counts, and micro-USD credit movements. Stripe payment identifiers arrive through signed webhook metadata so we can apply purchased credit. We do not store full card numbers.
To authenticate you, issue and revoke API keys, provide the API, and keep a prepaid balance. Usage records show what was deducted. Billing records show what was purchased. We use your email to operate the account and to reply if you write to us.
The site and API run on Cloudflare Workers. Account, session, key, and ledger rows are stored in Cloudflare D1. Card payments are processed by Stripe. We do not sell personal data, and we do not share it for advertising.
We keep account, key, usage, and ledger records while the account is open, and for a limited time afterward, so we can answer billing questions and limit abuse. To request deletion of your account and the personal data tied to it, sign in with the account email and ask for deletion from that same account. We may retain what we must keep for tax, fraud prevention, or other legal duties, including Stripe payment references.
The Terms of Service cover prepaid credits and acceptable use.
