Terms of Service

Pilos for Chrome · Last updated October 11, 2026

These terms cover the Pilos browser extension. Pilos Agents and Pilos Rooms have their own, at pilos.net/terms; nothing here replaces those. The privacy policy is the companion document and is the precise one — it says exactly what leaves your browser and when. These terms are about responsibility: yours, and ours.

By installing and using the extension you agree to these terms. If you do not, remove it.

1. Pilos acts in your browser, as you

This is the sentence everything else follows from.

Restyling changes how a page is displayed, for you and for nobody else. A view goes further: it asks the site’s own addresses for data using your own session, from inside the page, because that data is yours and sits behind your login. We have no copy of your credentials and no way to make those requests from anywhere but your browser.

Pilos never writes to a site. It does not post, click, follow, vote, submit a form or message on your behalf, and there is no shape in the format that describes a view that could express one of those.

2. Other people’s websites are their websites

Automated access to a site’s API is against most sites’ terms of service. A view asks a site for data on a schedule you set in motion, which many sites treat as automation whether or not you are logged in and whether or not the data is your own.

If a site objects, it objects to your account: rate limiting, a challenge, a suspension. That consequence lands on you and not on us, and we cannot appeal it for you. The panel says so before watching a site starts, and the honest advice is the same here: leave it switched off for any account you cannot afford to lose.

You are responsible for your use of any third-party site through Pilos, including whether that use is permitted by that site. Pilos limits what it does — reads only, one request a second, a cache, a cap on pages, and a tally you can read — but limiting is not permission, and we make no claim that using Pilos on a particular site is allowed by that site.

3. What Pilos writes for you, and what that means

For the cases its components cannot reach, Pilos writes a stylesheet and sometimes a small program in JavaScript, from your request.

• The program is shown to you in full before you keep the view. Reading it is the only real check, which is why it is the code and not a description of the code.
• It runs only if you switch on “Allow user scripts” yourself, in Chrome’s own settings. We cannot turn that on for you.
• It runs in a space with no access to the extension and no way to become more code, and it is handed only the rows the view already fetched.
• The checks on it are a tripwire, not a sandbox. A program runs beside the page, and the rules that say it may not reach the network or the site’s own markup are enforced by reading the code before it runs. That catches a mistake and an obvious evasion. It is not a security boundary, and we do not claim it is one.

So a program Pilos wrote may be wrong, may draw nothing, and may stop working when a site changes. We do not warrant that generated styling or code is correct, fit for a purpose, or free of defects. You decide whether to keep a view after reading what it carries.

A program is never accepted from anybody else. A shared view carries no code, and one that arrives with code is refused.

4. Your data is yours

Your changes, your views and the notes you type into them are yours. We claim no ownership of them and no licence to use them, beyond what is needed to provide the parts you switch on.

• Nothing leaves your browser by default. Your changes sync with your own Chrome profile; views, notes, the list of addresses Pilos has learned and the request tally stay on that machine.
• Connecting an account sends the hostnames and recipes of sites you have customised, so the dashboard can show them. Disconnecting stops it; deleting the account deletes them.
• Turning on syncing keeps a copy of your views and notes against your account, encrypted in your browser with a key we never receive. We cannot read it, and we cannot recover it: lose every browser that holds the key and the stored copy can never be opened again, by you or by us. There is no escrow, deliberately — an escrow we could open would be a server that can read your notes.
• Your own notes are never deleted by Pilos. Not by removing the view that created them, not by switching the feature off, not by forgetting the site. Only you can.

5. Sharing a view

When you share a view you publish it. The stored copy is readable by us, because it has to be served to a browser that holds none of your keys — it is the one thing in Pilos that is.

By sharing a view you confirm that you have the right to share it, and you give us permission to store it and serve it to anybody who has its code, until you stop sharing it. A shared view carries no program and none of your own rows.

You are responsible for what you share. We may remove a shared view without notice if it breaks these terms or the law, or if we are required to; removing it takes the code down and does not remove the view from anybody who has already installed it.

Taking in a shared view is your decision. Pilos shows you what it will read before you keep it, and that disclosure is computed from the view itself rather than written by whoever shared it — but it is still your judgement about somebody else’s idea, on your account.

6. Paying

Pilos is free for everyone at the moment. When the paid tier is switched on, Pro is a subscription billed monthly or yearly through Stripe, who collect your payment details directly — we never see a card number. Cancelling stops the next renewal and leaves Pro working until the end of the period you have paid for.

Your first site stays free permanently, whatever happens to a subscription, so the extension never becomes unusable because a payment lapsed. Prices can change; a change applies from your next renewal, never retroactively.

7. No warranty, and what we are liable for

The extension is provided as it is. We do not warrant that it works on any particular site, that a site will keep working the way a view expects, or that your changes will survive a site’s redesign — sites change without telling us, and a view built on an address a site stops serving will stop reading.

To the extent the law allows, we are not liable for indirect or consequential loss, for loss of data you had no other copy of, or for anything a third-party site does to your account. Nothing here limits liability that cannot be limited.

8. Stopping

You can stop at any time by removing the extension. Forget this site removes everything Pilos learned about a site; stop syncing forgets the key on that browser; remove the stored copy deletes the encrypted copy for the whole account; deleting your account removes the rows we hold, including anything you had shared.

We may suspend an account that breaks these terms, and we will try to say so first.

9. Changes to these terms

If these terms change in a way that matters, this page says when it was last updated, and the extension links to it. Continuing to use Pilos after a change means accepting it.

10. Law and contact

Governed by the laws of the State of Delaware, United States, without regard to conflict-of-law provisions — the same as the rest of Pilos.
