Privacy Policy

Last updated: August 13, 2026

This policy describes what data we collect, why, and what we do with it. The honest summary: almost nothing, on purpose.

In one paragraph: the SeeNote extension processes filings entirely inside your browser and sends us nothing about what you read. Its free trial is counted on your own device; the only thing that reaches us is a random install identifier and a number from 0 to 3. It has one optional setting, off by default, that shares anonymous aggregate counts (never URLs, tickers, or filing text). The only personal data we hold is the email address you give us if you sign up, which we use to email you about SeeNote. Unsubscribe at any time, or email us and we delete you from the list.

1. Data the extension collects: none by default

The SeeNote Chrome extension runs entirely locally on your device. It reads the filing page you are viewing, on sec.gov or on one of the three other filing surfaces listed below, to make footnote cross-references clickable, and that processing never leaves your browser. Specifically, the extension:

Which filings you read is your business. By design, we cannot see it.

One optional setting, off by default. The extension's settings include a "Share anonymous usage counts" toggle. It stays disabled unless you turn it on. When enabled, SeeNote sends only aggregate counters (for example, "42 references resolved in 10-K filings") that contain no URLs, no company or ticker identifiers, no filing text, and no personal data. You can turn it off again at any time. The verbatim note you read in a popup is never transmitted.

The SeeNote Reader opens filing PDFs you choose (via the toolbar, a right-click, or drag-and-drop) and processes them entirely in your browser. The PDF is never uploaded. The same off-by-default anonymous usage-count setting applies; nothing about which PDF you open is sent.

Highlights and notes you write yourself. You can mark a passage in a filing and attach a note to it. What that stores is the passage you quoted, your note, the filing’s title and address, and the time you last changed it. All of it is written unencrypted into Chrome’s local storage on the device you marked it on — the same place the extension keeps its settings. It is never synced to another computer, never transmitted to us or to anyone else, and it is deleted along with everything else the extension holds when you remove the extension. Anyone with access to your Chrome profile can read it, so treat a mark the way you would treat a note written in the margin of a printout.

The free trial, and the only thing it sends. SeeNote’s trial covers your first three filings. Which three is worked out and remembered on your device: the extension stores a one-way hash of each filing’s identity in your browser’s own storage, and mirrors that list through Chrome’s own sync so a second computer continues the same trial rather than starting a new one. So that clearing your browser storage does not silently hand out a second trial, the extension also registers the trial with us. That registration contains exactly and only:

That is the complete list. No filing identities ever leave your browser — not even hashed. No note identifiers, no record of which notes you opened, no timestamps of when you read anything. We can see that somebody has used two of three filings; we cannot see which filings, which notes, which company, or when. If any of those calls fail, the trial simply carries on working offline — the count on your device is the one that matters.

2. Data the website collects: your email, if you give it

If you ask to be emailed at launch — on seenote.co, or from the optional field in the extension’s welcome screen — we collect the email address you enter and nothing else. That is the whole record. Giving it is optional in both places, and nothing about SeeNote works differently if you skip it.

The signup form is the only thing on this site that collects data by default. We load no analytics scripts, no advertising pixels and no social media trackers unless you have opted into the matching category in the cookie banner described in section 3 — and until you do, none of them are present on the page at all.

Subscribing is handled by our payment processor at its own checkout, under its own privacy policy. We never see or store your card details.

3. Cookies and your choices

By default this site sets no tracking cookies. A consent banner lets you choose which optional categories, if any, you allow:

Nothing in an optional category loads unless you opt in. Your choice is stored on your own device and you can change it any time via the "Cookie preferences" link in the footer.

4. What we use your email for

Every email we send includes an unsubscribe link. We will never sell, rent, or trade your email address to anyone.

5. Where your data lives

Signup data is stored in a Cloudflare D1 database and processed by Cloudflare Workers (our infrastructure provider) and Brevo (our email delivery provider). Both act as processors on our behalf and are bound by their own data processing agreements. We do not share your data with any other third party unless required by law or a court order.

6. Retention and deletion

We keep your email address until you unsubscribe or ask us to delete it. Unsubscribing stops all emails immediately; if you want the record fully deleted from our database, email hello@seenote.co and we will delete it within 14 days and confirm.

7. Your rights

You have the right to access the data we hold about you, correct it, or have it deleted, under applicable data protection law, including the GDPR if you are in the EU/EEA or UK and the CCPA if you are a California resident. Given what we collect, exercising any of these amounts to one email to hello@seenote.co.

8. Security

All traffic to seenote.co and our API is encrypted (HTTPS/TLS). Access to the subscriber database is restricted by authenticated tokens held only by the operator. We hold no passwords and no payment data: there is no account system, and payments at launch will be handled by a dedicated payment processor that does not share card details with us.

9. Children

SeeNote is a professional tool for reading securities filings and is not directed at children under 18. We do not knowingly collect data from children.

10. Changes

If we change this policy, we will update the date at the top. If a change is material, for example if a future version of the extension ever collects any data, we will say so prominently, and it will remain true that the verbatim reading experience sends nothing anywhere.
