PromptNest is a Chrome extension for saving, organizing, and inserting AI prompts. This policy explains what data PromptNest handles and where it goes.
- PromptNest is local-first. By default, everything you create is stored only on your device.
- No account is required. Nothing leaves your browser unless you sign in.
- Cloud sync is optional and invite-only. Only if you sign in with Google and your account has been granted sync access is your data sent to our server.
- We do not sell data, show ads, or use third-party analytics or trackers.
Your prompts, categories, tags, settings, and usage counts (how often you use each prompt) are stored on your device using Chrome's extension storage (chrome.storage.local). This data stays in your browser and is not transmitted anywhere unless you enable cloud sync by signing in.
If you choose to sign in with Google, we receive and store:
- Account information: your email address, name, and profile picture URL, provided by Google after you consent on Google's sign-in screen.
- Authentication data: a session token used to authenticate your requests to the PromptNest API.
Sign-in access is restricted to invited accounts. If your account has not been invited, our server rejects the sign-in and does not store your email or create any account record; the extension continues to work fully in local-only mode.
For invited accounts that sign in, PromptNest syncs your prompts and categories (including titles, prompt text, tags, pinned status, timestamps, and usage counts, and — for prompts saved via the right-click menu — the page URL and title they were saved from) to our backend so they are available on your other devices.
- Where it is stored: on Cloudflare's infrastructure (Cloudflare Workers and a Cloudflare D1 database) operated by us.
- What it is used for: solely to provide cross-device sync of your own data. Nothing else.
- We do not sell or rent your data to anyone.
- We do not use your data for advertising or profiling.
- We do not use third-party analytics or tracking in the extension.
- We do not read the pages you visit. The extension's content script runs only on six supported AI chat sites, and only to insert prompt text you choose into the chat box and to show a launcher button.
- We do not transfer your data to third parties except the hosting infrastructure (Cloudflare) required to operate the sync service.
- Trash: deleted prompts and categories are kept in Trash for 15 days (locally and, for synced accounts, on the server), then permanently removed. You can also permanently delete items immediately.
- Sign-out: signing out removes your session from the browser.
- Account deletion: you may request deletion of your account and all synced data at any time by contacting shshawon39@gmail.com; deletion is also available through the extension's API (
DELETE /auth/account). Deletion removes your account record, prompts, and categories from our database.
Communication with the PromptNest API uses HTTPS. Sign-in is verified against Google's OAuth service, and API sessions use signed, expiring tokens.
PromptNest is not directed at children under 13 and does not knowingly collect data from them.
If this policy changes, the updated version will be posted at this URL with a new effective date.
