Privacy Policy

Updated 21 September 2026

In short: the extensions run in your browser, keep your data on your device, and never send it to a PI Labs server. The website holds one thing about you: who you are and whether your subscription is active.

This policy covers the PI Labs website at pilabs.space and the browser extensions published by PI Labs (“we”, “us”, “our”):

It replaces the earlier Joelbooks extensions privacy policy for these products. Where this policy and any general Joelbooks policy differ, this one governs.

The short version. We operate no server that receives, stores, or processes the content you work on in the extensions. We do not sell your data and we do not use it for advertising. Your settings and content stay in your browser’s local storage. Some extensions can, at your choice, send text you select to a third-party AI provider, or sync your data to your own Google Drive. The website itself stores your Google account identity and your subscription status, and nothing else. Each case is described below.

1. What the website collects

You can install and use every free feature without ever visiting the website or creating an account. An account exists for one reason: so premium can follow you between machines.

When you sign in with Google

We receive and store:

We use these only to recognise you when you return, to link your subscription to you, and to answer you if you contact support. We do not receive your Google password, and we cannot read anything else in your Google account.

When you subscribe

Payments are handled entirely by our payment providers. We never see or store your card number, bank details, or wallet keys. What we store is your subscription status, the plan, the current period end date, and the provider’s reference for your subscription. That is enough to answer the only question the extensions ask, which is whether premium is currently active for your account.

When you just visit

The site is hosted on Vercel, which records standard server request logs (IP address, user agent, requested page) for security and reliability. We do not run advertising trackers, we do not set marketing cookies, and we do not build a profile of your browsing.

2. What the extensions collect

We do not collect, receive, or store the content you work on in the extensions. Each one keeps what it needs in your own browser using Chrome’s storage API, or, only when you choose, in your own Google Drive account.

Depending on the extension, the data held locally may include:

This information is stored on your device. Uninstalling the extension, or clearing its storage, removes it.

3. How each extension handles data

PI Prompts: optional Google sign-in to sync to your own Drive

A prompt library that inserts saved prompts into LLM websites such as ChatGPT, Claude, Gemini, Grok, DeepSeek, Mistral, Qwen and others. Your prompts are stored in your browser.

Optionally, you can sign in with Google so your library syncs across devices. Sync uses a private application folder in your own Google Drive, a hidden folder only this extension can reach. Signing in reads your basic Google profile (name and email) to identify your account.

PI Fix Grammar: on-device by default, optional cloud fallback

Corrects grammar in a text field. By default it uses Chrome’s built-in on-device AI (Gemini Nano), which runs entirely on your computer, so your text never leaves your device.

As an optional fallback you may enter your own API key for a cloud provider (Groq, OpenRouter, or Google Gemini). If you enable this, the text you correct is sent directly to the provider you configured.

PI Summarize: sends selected text to an AI provider you choose

Adds a right-click Summarize option. When you use it, the extension opens your chosen AI chat service (ChatGPT, Gemini or Claude) and places the text you selected into that service’s chat box.

PI Answer: on-device by default, optional cloud fallback

Drafts a reply to a post on X. Like PI Fix Grammar it uses Chrome’s built-in on-device AI first, so by default nothing leaves your computer. You may optionally supply your own key for Groq, Google Gemini or OpenRouter as a fallback.

To write a reply it reads the post you are replying to and whatever you have already typed in the reply box. That post is passed to the model as data, wrapped in markers, with an explicit instruction not to follow anything it says.

Aviary: runs locally, no data sent out

Turns your own X analytics and creator-rewards figures into a daily flight progress view. It reads the figures already shown on the X pages you visit and stores your progress in your browser.

4. Summary of data flows

In no case is the content you work on sent to a PI Labs server. We have no access to the text you process, the prompts you save, or the replies you write.

5. Third-party services

When you choose a feature that involves a third party, that party’s own privacy policy applies to how they handle it:

6. How we use data

The extensions use locally stored data only to provide their features to you. The website uses your account data only to sign you in, to keep your subscription working, and to contact you about that subscription. We do not:

7. Retention and deletion

Locally stored data stays in your browser until you remove it. You can:

For your PI Labs account: write to us and we will delete it. Deleting your account ends premium access. We keep the minimum billing and tax records our payment providers and the law require, and on-chain USDC transactions remain public on the blockchain regardless.

8. Your rights

If you are in the UK, EU, or another region with similar law, you have the right to ask what we hold about you, to have it corrected, to have it deleted, and to receive a copy. Because we hold so little, just your Google identity and your subscription status, these requests are quick to answer. Write to hello@pilabs.space.

9. Children

These products are not directed to children under 16, and we do not knowingly collect personal information from children.

10. Security

Data stored by the extensions is protected by your browser’s and operating system’s security. Data you send to a third-party AI provider, to Google Drive, or to us travels over encrypted (HTTPS) connections. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

11. Changes to this policy

We may update this policy from time to time. When we do, we will revise the “Updated” date above. Material changes may also be reflected in the extensions’ store listings.
