PromptBeaver — Privacy Policy

PromptBeaver is a Chrome extension that turns rough ideas into structured prompts for AI coding assistants (Claude, ChatGPT, Gemini). This policy explains exactly what data the extension collects, where it goes, and how to remove it.

Information collected

PromptBeaver stores the following data locally on your device via chrome.storage.local:

• Anonymous installation ID — a randomly generated UUID created on first run. Not linked to any personal information; used only to associate your verified subscription state with this installation.
• Prompt history — the rough ideas you type and the structured prompts the extension generates. Held only on your device. You can delete individual entries or clear the entire history from inside the extension at any time.
• Theme preference — light or dark.
• Cached subscription state — the most recent plan response from our backend (Free or Pro), along with its verification timestamp.

We do not collect:

• Names, email addresses, IP addresses, or other personally identifying information.
• Browsing history, page content, cookies, or any data outside chrome.storage.local.
• Analytics events, telemetry, or behavioral tracking.
• Crash reports.

Information transmitted

PromptBeaver makes network requests only to its own backend at https://promptbeaver-api.weihao-fu626.workers.dev. The transmitted payload is limited to:

• Plan check (GET /v1/me/plan) — sends the anonymous installation ID; receives { plan, quotaLabel, historyLimit, promptCharLimit }.
• Checkout creation (POST /v1/checkout/create) — sends the anonymous installation ID; receives a Stripe Checkout URL.

Your prompt input and generated output are never transmitted to our backend or any third party. All prompt generation happens locally inside the extension.

Third parties

• Stripe — handles payment processing if you choose to upgrade to Pro. When you click "Upgrade to Pro", you are redirected to Stripe's hosted checkout page; payment information is collected and stored by Stripe under their own privacy policy. PromptBeaver never sees your card details.
• Cloudflare Workers — hosts the PromptBeaver backend. Standard request logs (IP, user agent, timestamp) may be retained by Cloudflare per their infrastructure policies.

No data is sold or shared with advertisers, data brokers, or any other third party.

Data retention and deletion

• Local data is held until you clear it from inside the extension or uninstall the extension. Uninstalling removes all local data.
• Subscription records on our backend are keyed by your anonymous installation ID and retained for as long as your subscription is active. To request deletion of your subscription record after canceling, email the contact below.

Permissions

• storage — required to remember your prompt history, theme, and verified plan state across sessions.
• host_permissions: https://promptbeaver-api.weihao-fu626.workers.dev/* — required to verify your subscription status and create a Stripe Checkout session. This is the only remote host the extension contacts.

Children

PromptBeaver is not directed at children under 13 and does not knowingly collect data from children.

Changes to this policy

We will update this page if our data practices change. The "Last updated" date at the top reflects the most recent revision.
