Privacy

Your draft stays
in your browser.

Fold has no account, no database and no cookies. One thing here can send your writing somewhere else, you have to press a button that says so, and this page is where it is written down.

On your device

The draft you type, the proof sheet, the fold measurement, the character counts, the formatting and the note on your opening line are all worked out in the browser. None of it is sent anywhere, none of it is written to storage, and closing the tab ends it.

The share link

Share proof puts the entire draft inside the link. Nothing is stored at our end - the text travels in the address itself - which also means anyone with the link can read the post, and that the link sits in browser history and in whatever it is pasted into. A warning says so before it is copied.

The one thing that leaves

Three other first lines works offline: it moves sentences you already wrote to the front, using rules in the page. Underneath it is a second button that sends your draft to Anthropic’s API so a model can write three new openings. That is the only thing you type that ever leaves your browser, and it only happens when you press it.

We do not log it, store it or keep a record of it at our end. Anthropic’s commercial terms say they may not train models on it, and that is the part we can point at. What we cannot tell you is that it vanishes: Anthropic does not offer ad hoc deletion on API data, so your draft is held on their systems for a period set by their retention policy rather than by us. Anthropic is a US company and the request is processed outside the UK. If you would rather none of that happened, do not press that button - everything else on this page works without it.

This page used to say the draft was “not retained beyond serving the request”. That was more than Anthropic’s terms actually promise, and it was corrected on 16 September 2026 rather than quietly reworded.

The only thing recorded about the request is a count, kept against your IP address for an hour so one visitor cannot run up a bill for everyone. The count is a number; it carries nothing you wrote. That counter runs on Upstash, so your IP address reaches them for that hour - they are the one other company in this list, and they never see the draft.

Measurement

Fold counts visits with Vercel Web Analytics. It sets no cookies and no storage of any kind, and it has no identifier for you - a visit is counted against a hash of the request that is thrown away within the day, so we cannot tell a returning visitor from a new one, and we cannot follow anyone between our tools. We checked that ourselves rather than taking the supplier’s word for it.

The address bar is stripped before anything is sent, so a share link never carries your draft into it. Beyond that it counts five things: formatting applied, a copy taken, the device switched, a rewrite asked for, a link shared. Nothing you write is ever part of an event.

Until 17 September 2026 this page was wrong about that. It said Fold used Google Analytics “configured to set no cookies at all”, on the strength of a setting called client_storage: "none". That setting does nothing: it belongs to an older version of Google Analytics, and the current one writes a cookie regardless. We found it by wiping the cookies, reloading and watching them come back. Google Analytics has now been removed from this tool altogether, which is what made the sentence at the top of this page true.

Your IP address reaches Vercel, who host Fold, as part of any request to any website, and is used for approximate location and for the rate limit above. We do not store it ourselves.

Asking

Fold is made by Digitopia Design Ltd, a company registered in England and Wales, number 12037302, registered office 124 City Road, London, EC1V 2NX, trading as Digitopia Labs. Our ICO registration is ZC160761. That is the same company named at the foot of every page here. For anything on this page, or to ask what we hold about you (which should be nothing), write to hello@digitopiadesign.com.

We rely on legitimate interests for both kinds of counting: the request count, so one visitor cannot run up the bill for everyone, and the five analytics events, so we know which parts of the tool get used. The counting is done by Vercel, who host this tool, so it goes no further than the company already serving you the page. Vercel is a US company, so that processing happens outside the UK under the standard contractual clauses in their data processing terms.

You can ask for a copy of anything held about you, ask for it to be erased, or object to the counting altogether, at the same address. If you think we have got something on this page wrong, you can also complain to the Information Commissioner’s Office at ico.org.uk.
