Privacy Policy | Notebooker.ai

Last updated: June 3, 2026

Notebooker (“we”, “us”, “our”) provides an AI-powered notebook service available at notebooker.ai and app.notebooker.ai, along with companion browser extensions and desktop, mobile, and command-line clients. This Privacy Policy explains what we collect, how we use it, and the choices you have.

By using Notebooker you agree to the practices described below. If you do not agree, please do not use the service.

What we collect

Account information. When you create an account we store your email address and an encrypted password (or, if you sign in with a third party such as Google or Apple, the identifier they return to us). We may also store a display name and profile image if you choose to provide them.

Content you save. Notebooker is, by design, a place to keep things — links, notes, PDFs, audio files, transcripts, and the chats and podcasts you generate from them. We store this content so we can show it back to you across your devices.

Usage data. We log basic events about how the service is used (pages viewed, features triggered, error reports, approximate location derived from IP). We use this to keep the service running, debug issues, and improve the product.

Billing data. If you subscribe to a paid plan, our payment processor (Stripe) handles your card details directly. We never see or store your full card number; we receive only a token and limited metadata such as the last four digits, brand, and country.

Cookies and similar technologies. We use a small number of essential cookies to keep you signed in and remember your preferences. We do not use third-party advertising or cross-site tracking cookies.

How we use your data

We use the information described above to:

Run the service: store your notebooks, sync across devices, generate AI responses and podcasts, and deliver the features you use.
Communicate with you: respond to support requests and send important account or service notices. Marketing emails are opt-in and you can unsubscribe at any time.
Keep things working: monitor uptime, investigate bugs, prevent abuse and fraud.
Bill you for paid plans.
Comply with our legal obligations.

AI providers and the “bring your own key” option

Some Notebooker features rely on third-party AI models. When you use one of these features, the relevant inputs (such as the text of a source you’re chatting with, or a prompt you wrote) are sent to the model provider so they can return a response.

You can supply your own API keys for supported providers. When you do, requests go directly to that provider under your account, and we do not retain the request or response server-side beyond what is necessary to display the result to you. If you use Notebooker’s hosted AI credits instead, requests go to the same providers through our infrastructure.

We do not sell, rent, or otherwise share your content with model providers for the purpose of training their general-purpose models, and we ask our providers to honor the same.

Service providers and sub-processors

We rely on a handful of vendors to operate the service, including hosting (Laravel Cloud, Cloudflare), payment processing (Stripe), transactional email, and the AI providers you choose to use. These vendors process data on our behalf under written agreements and are not permitted to use it for their own purposes.

We do not sell your personal information, and we do not share it with advertisers. We may share data only in the limited circumstances below:

With service providers as described above.
With other people you explicitly share content with (for example, a public notebook link you create).
If required by law, regulation, legal process, or a valid governmental request, or to protect the rights, property, or safety of Notebooker, our users, or the public.
In connection with a merger, acquisition, or sale of assets, in which case we will give you notice before your data is transferred and becomes subject to a different privacy policy.

How long we keep your data

We keep your account data and content for as long as your account is active. If you delete an item, we remove it from active systems promptly, though copies may remain in backups for a limited period before being overwritten. If you delete your account, we delete or anonymize your personal information within a reasonable time, except where we are required to retain something for legal, accounting, or fraud-prevention reasons.

Your choices

Access and export. You can view your content in the app at any time, and request an export by emailing us.
Correction. You can update your profile from inside the app, or write to us if something we hold about you is wrong.
Deletion. You can delete individual items, or your entire account, from inside the app.
Email preferences. You can opt out of marketing emails using the unsubscribe link in any such message; account and security notices are not optional.
Regional rights. Depending on where you live (for example, the EEA, UK, California), you may have additional rights under laws like GDPR or CCPA — including the right to object to processing, restrict processing, or lodge a complaint with a regulator. To exercise any of these, contact us at the address below.

Security

We use industry-standard measures to protect your data, including TLS in transit, encryption at rest, scoped access controls, and routine review of our infrastructure. No system is perfectly secure, and we cannot guarantee absolute security, but we work hard to keep your information safe.

Children

Notebooker is not directed at children under 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal information from them. If you believe a child has provided us with information, please contact us so we can remove it.

International transfers

Notebooker is operated from the United States, and your data may be processed in countries other than the one you live in. Where required, we rely on appropriate safeguards (such as standard contractual clauses) for international transfers.

Changes to this policy

We may update this Privacy Policy from time to time. When we do, we’ll update the “Last updated” date at the top, and for material changes we’ll provide a more prominent notice (for example, by email or an in-app banner).
