When

After you save a key, when you start to fold a paragraph that has no AI summary yet. No page text leaves before that. With translated folds on, which is the default, after you fold a paragraph written in another language, folding more or reading on also sends the next paragraphs you have not folded yet, ahead of time. They can be under the next heading.

What

That paragraph, up to seven neighbors in its section (two when folding with translation), the page title and the page's headings. The page address is not part of the request.

Where

Straight to the service you chose, not through tfold: apis.opengateway.ai (OpenGateway) or openrouter.ai (OpenRouter), with your key. If it is busy or unreachable and a key for the other one is saved, the same text goes there.

Keys

When you save a key, it goes to its service to check that it works. No page text goes with it.

Like any web request, the service can also see your IP address. These services may pass the text on to the company that runs the AI model. You can change the model in settings. What they do with the text is up to the policies of OpenGateway and OpenRouter.

With no key saved, page text goes nowhere. Quick summaries are made inside your browser.

While tfold is on, it looks at the page's paragraphs inside your browser to find the one you point at. Looking sends nothing out.

The test paragraph in settings has summaries built in or made inside your browser. Folding it sends nothing.

Extension storage

Your API keys, chosen service and model, the sites where tfold is off, your shortcuts and scroll key, and whether you saw the hint and have folded before. Pages you read cannot get them.

Chrome sync storage

Your language setting and whether auto-translate is on. If Chrome sync is on, they follow your Google account to your other Chrome browsers.

Summary store

The AI summaries you already received, the original sentences of those paragraphs, and each page's address, including anything after a question mark. This includes neighbors you have not folded yet. It keeps the same paragraph from being sent again in most cases. It has no set expiry and goes away when you remove the extension.

None of this goes to tfold. tfold has no server to receive it yet.

This website sets no cookies and loads no outside resources. It has no input fields. Its only scripts are its own: they draw the background and open the menu, and they send nothing. Cloudflare serves it, so Cloudflare sees your IP address and the page you asked for in order to answer the request.

Email to admin@tfold.xyz passes through Cloudflare Email Routing and arrives in Jinu Kim's Gmail mailbox.

These do not exist yet, and today we hold none of this data. This is the current plan.

Sign-in

Google sign-in gives us your email address and Google account identifier.

tfold server

Stores, on Cloudflare, your account, plan status, trial end date, the percent left this month and its reset date, your credit balance, and your Paddle customer and subscription identifiers.

Pro AI summaries

The same text as today (the paragraph, its neighbors, the title and headings) goes to the tfold server, which asks an AI service. Which AI service Pro uses, whether the server stores paragraph text and for how long, and how long it keeps request records are not decided. We will state this here before Pro opens.

Payment

Paddle takes your card details directly. The tfold server does not receive card numbers. Paddle's privacy notice covers how Paddle handles them.

• Making summaries: sending the paragraphs you fold and their neighbors to an AI service.
• Accounts and billing (later): checking sign-in and plan status.
• Answering you: replying to email you send.

• OpenGateway and OpenRouter, when you use your own key.
• Cloudflare, to run the site and forward email, and later to run the server.
• Google, for the mailbox, and later for sign-in. If Chrome sync is on, your language and auto-translate settings also go to your Google account.
• Paddle, later, as Merchant of Record for payment and tax.
• Professional advisers and authorities, only where the law requires it.

Request data at Cloudflare

tfold keeps no request records of its own for this site. Cloudflare's privacy policy covers what Cloudflare does.

Support email

Kept for 3 years after we finish handling it.

Account data (later)

Deleted within 30 days of account deletion. Payment records are kept for the legally required period.

Paragraph text and request records on the server (later)

We will state this here before Pro opens.

Today your data can go to these places:

• With your own key, the extension sends text straight to the service you chose, OpenGateway or OpenRouter.
• Cloudflare serves this site.
• Email to admin@tfold.xyz is handled by Cloudflare Email Routing and Gmail.

These services may process data outside the country where you live. Each service decides where it does so.

Depending on where you live, you can ask to see, correct or delete your data, or to stop its use. You can also withdraw consent or complain to a supervisory authority. Email admin@tfold.xyz.

Removing the extension removes what it stored in your browser.

We answer each request within 30 days.

The site and requests to AI services use HTTPS. API keys stay in extension storage, where pages you read cannot get them. We work to protect data, but no method is perfect.

When this notice changes, this page shows the new text and date.
