What Wellspring holds about you, and what it does not.

Effective 19 September 2026. Wellspring is operated by U3 Labs, LLC, a small studio in Florida, United States. This page says only what the product actually does today; it will be updated, with the date changed, before anything below changes.

The short version

What is stored, and where

Everything you make in Wellspring is kept in your browser’s local storage under the key wellspring-v1 (and, if you set one, the study assistant’s endpoint key under wellspring-assistant-key). It stays on your device. Clearing your browser’s site data removes it; a private or incognito window discards it when closed. You can export it as a file at any time and delete all of it with one control in Settings. Your data explains both.

What reaches a server

The site itself. Wellspring is static files served by a hosting provider. Like every web host, that provider may keep standard access logs — your IP address, the time, and the files requested — for security and operation. Wellspring does not read, analyse, share or sell those logs, and does not use them to identify anyone.

Type and assets are served from Wellspring’s own site. No fonts or scripts are requested from third parties when you use the product.

The study assistant, only if you turn it on. Choosing “On this device” downloads an open language model and its runtime once, from the MLC model hub (Hugging Face) and the jsDelivr CDN, into your browser; those services see the download request. After that, nothing you write leaves your machine — the model runs locally. Choosing “An endpoint” sends the section you ask about, and the guidance shown with it, to the address you entered — a community’s server or a provider where you hold a key. That host’s data terms apply, not ours. The address and any key are stored only in your browser and are never included in a research backup.

Support, only if you choose to give. Contributions are taken by Stripe on Stripe’s own page. Stripe receives your card details, name and email and is the controller of that data under its own policy; Wellspring receives a record that a contribution was made and the email address Stripe reports, and keeps nothing else. No card details ever reach Wellspring.

Links out. Some sources link to the archives they come from (the Internet Archive, CCEL, Coptic SCRIPTORIUM and others). Following a link takes you to that site under its own policy.

What we do not do

We do not collect names, email addresses or any personal information through the product. We do not set cookies. We do not run analytics or advertising. We do not sell, rent or share data, because we hold none. We do not profile, and nothing in Wellspring is personalised by anyone but you.

Children

Wellspring is a research tool for adults and is not directed to children under 13. We do not knowingly collect information from anyone, of any age.

What will change when accounts arrive

At public launch, Wellspring will require a free account to use the workspace and the library — so that your research follows you between devices, and so that two people sharing one computer never see each other’s work. The account is free; nothing in Wellspring is paid for. Before that ships, this page will be updated first, and it will say: what is stored on our servers (your research and the email address or Google identity you sign in with), where (a database provider under contract to us, in the United States), how you sign in (Google, or a code sent to your email), how to export and delete everything, and how to contact us about it. The public site, Help and these pages remain readable without an account.

Your rights and how to use them

Because your research is on your own device, you can see, export and delete it yourself, without asking anyone. If you have a question about this page, or believe we hold something about you that we should not, write to privacy@wellspringstudy.org. Depending on where you live you may have legal rights to access, correct, export or erase personal data and to complain to a supervisory authority; we will honour requests under those laws.

Who we are

U3 Labs, LLC, Florida, United States, operates Wellspring. The founder’s intention is for Wellspring to become an independent nonprofit foundation in time; if that happens, this page will name it and say what changes. Contact: the contact page.

Changes

When this page changes, the effective date at the top changes with it and the previous text stays available on request. We do not make retroactive changes to how data already held is used, because we hold none.
