Q: What counts as a "create"?

Each successful POST /api/secrets call — whether via the web app, CLI, SDK, or direct API — counts as one create against your monthly quota. A secret that is never retrieved still counts.

Q: What happens when I hit my monthly limit?

The API returns a 429 MONTHLY_LIMIT_EXCEEDED response. Existing secrets remain accessible — only new creates are blocked until the month resets. Your account page shows current usage and the exact reset date.

Common questions

Is my data ever decrypted on your servers?

No. Zephr uses client-side AES-GCM-256 encryption. Your plaintext never leaves your device — the server stores only ciphertext and never has access to your encryption key. The key travels in the URL fragment, which browsers do not send to servers.

What's the difference between Dev and Pro?

Both tiers include sub-hour expiry (5m, 15m, 30m) for pipeline-native workflows. Dev is built for individual developers and automation scripts: 2,000 creates/month and up to 200KB per secret. Pro is for high-volume pipelines and agent workflows: 50,000 creates/month and up to 1MB per secret.

Do I need a credit card to get started?

No. The Free tier requires only an email address — no card, no commitment. A card is only required when upgrading to Dev or Pro.

Is the MCP server, CLI, or SDK priced separately?

No — MCP server, CLI, SDK, and web all draw from the same monthly quota. Use whichever surface fits your workflow.

What happens when I hit my monthly limit?

The API returns a 429 MONTHLY_LIMIT_EXCEEDED response. Existing secrets remain accessible — only new creates are blocked until the month resets. Your account page shows current usage and the exact reset date.

Do unused creates roll over?

No. Quotas reset on the first day of each calendar month regardless of usage.

Can I cancel at any time?

Yes. Cancel from the billing portal in your account settings. Access continues until the end of the current billing period. New subscriptions are covered by a 30-day refund policy.
