Privacy policy: Texwell LaTeX Equations
For the Texwell LaTeX Equations add-in for Microsoft Word and PowerPoint. Last updated October 2, 2026.
Texwell LaTeX Equations ("Texwell") is made by Great Work LLC ("we"). This page explains what Texwell handles, where, and for how long. In short: your equations and documents stay on your computer; our server only knows who you are (from Microsoft sign-in or a license key) and how many equations you've inserted, so it can run your trial and subscription.
What stays on your computer
- Your documents and equations. Texwell turns LaTeX into equations inside the Texwell pane, in your own browser or Office app. The LaTeX you type is never sent to us or anyone else.
- LaTeX saved with each equation, so you can edit it later: in the document's add-in settings (Word equations), in a picture's alt text (pictures), or in a PowerPoint shape's tags. It travels with the document, like any other content you put in it.
- Your equation library, recent equations and pane settings (size, color, layout): in your browser's local storage on that computer. Export or delete them from the pane any time; clearing your browser data removes them.
Texwell reads and changes only the document you open it in, and only when you click something in the pane or ribbon. It can't open your other files, your email, your calendar or your OneDrive.
What our server receives
Licensing runs on our server at addons.greatwork.company, operated by Great Work LLC in the United States (DigitalOcean data center in New York).
| Data | Why | Kept |
|---|---|---|
| From Microsoft sign-in (an ID token for the scopes openid, profile, email): your Microsoft account's object id and tenant (organization) id, your name and email address | To keep your trial and subscription with your account across computers. The account and tenant ids are the key; the email address is shown to you and used to contact you about billing. | Until you ask us to delete it |
| How many equations you've inserted during the trial, and when the trial started | To run the trial (25 equations or 14 days) | Until you ask us to delete it |
| Subscription and payment status from Stripe (plan, status, renewal date, Stripe customer id, number of seats), and for team plans the email addresses of members the buyer assigns to seats | To unlock Texwell for paid users and their team | As long as accounting and tax law require (up to 7 years for billing records) |
| For license keys: a one-way fingerprint of the key (we never store the key itself), the buyer's email, and each activation's random device id and label such as "Windows PC" | To check the key and limit how many computers use it | While the key exists; ask us to delete it |
| Your IP address, briefly | To limit abuse (rate limits on sign-in, key activation and billing pages) | Rate-limit counters: minutes, in memory. Web server access logs: rotated away after 14 days |
We don't receive your documents, your equations, or anything from Microsoft Graph. We don't use advertising or analytics trackers, and we don't sell or share personal data.
Other companies involved
- Microsoft signs you in (Microsoft Entra ID / Microsoft account) and runs Word and PowerPoint. Microsoft's privacy statement applies to that.
- Stripe processes payments. Card details go to Stripe directly; we never see them. Stripe's privacy policy applies.
- Resend sends the emails you ask for (your license key, a billing link).
- DigitalOcean hosts our server.
Your choices and rights
- Sign out in the Texwell pane any time; that clears the sign-in on that computer.
- Ask us to see, correct, export or delete the data we hold about you: email hello@greatwork.company. We reply within one business day and act within 30 days. Billing records we must keep by law are kept only for that purpose.
- Cancel your subscription in Manage billing; we stop billing at the end of the paid period. Trial and account records are deleted within 30 days of a deletion request; billing records are kept only as long as the law requires.
Children
Texwell is a tool for students and teachers. It doesn't ask for age and stores no data from documents. School accounts sign in through their school's Microsoft organization, which controls whether add-ins may be used.
Changes
If this policy changes in a way that affects what we collect, we'll update the date above and say so in the add-in.
