Privacy Policy
Last updated October 16, 2026. Draft for legal review.
The short version
- Your documents are yours. We use them only to analyze them for you.
- Your writing is never sold, never used to train AI models, and never sent to an outside AI service. Prosemetry runs its own measures on its own server.
- Without an account, results are deleted after 24 hours. With an account, you can download or delete everything whenever you like.
- We use one cookie, to keep you signed in. There’s no advertising and no tracking.
Who we are
Prosemetry is run by P8 Analytics, LLC, 304 W 15th Ave., Pine Bluff, AR 71601-5724. Questions about privacy go to hello@prosemetry.com.
What we collect, and why
| What | Why | How long we keep it |
|---|---|---|
| Documents you upload and the results of analyzing them, including your Workspace revisions and decisions | To provide the analysis, the Workspace and Compare | Free plan and visitors without an account: 24 hours. Basic: a week. Pro: 30 days. Sooner if you delete them or your account. |
| Your email address and a scrambled (hashed) form of your password | To sign you in, and to send account emails: confirming your address, resetting your password | Until you delete your account |
| Your plan and a record of when you ran each analysis | To apply your plan’s allowance | Until you delete your account |
| Your network (IP) address, for analyses run without an account | To stop one network from overusing the free plan | 48 hours |
| Server logs: time, network address and page requested | Security and fixing problems | Up to 14 days |
| Daily totals: how many times each page was opened, how many visitors came, which websites linked to us (the site’s name only), and answers to “Was this note helpful?” (the kind of note and the answer only) | To see how Prosemetry is used and make it better. These are counts; nothing in them identifies you, and no cookie is used | As long as they’re useful |
| Your email address, if you subscribe to updates | To send you news about Prosemetry | Until you unsubscribe |
| Billing details, on paid plans | To take payment. Card numbers go straight to our payment processor; we never see or store them. | As the law requires for financial records |
We don’t collect anything else about you, and we don’t buy data about you from anyone.
What we don’t do with your writing
- We don’t sell it, rent it or share it with advertisers.
- We don’t use it to train AI models, ours or anyone else’s.
- We don’t send it to outside AI services. Spelling checks and every measure run on Prosemetry’s own server.
- We don’t read it, except when you ask us to look into a problem with a specific analysis.
- We don’t rewrite it. Prosemetry describes your writing; the revising is yours.
Who else handles your information
We use a small number of service providers, each only for the job named here:
- Hetzner Online hosts our server in Helsinki, Finland, in the European Union. Your documents and account are stored there.
- An email delivery service receives your email address and the text of account emails, to deliver them. We use Resend (resend.com).
- A payment processor (Stripe) handles card payments directly.
We share information with others only if the law requires it, and then only what it requires. If Prosemetry is ever sold or merged, this policy continues to protect what we hold, and we’ll tell you before anything changes.
Cookies
Prosemetry sets one cookie, prosemetry_session. It keeps you signed in, or, without an account, connects you to the analyses you started in that browser. It’s essential for the site to work, so we don’t ask for consent. It lasts up to 180 days or until you sign out. The site also remembers a few preferences in your browser’s own storage, such as your place in a document. That information stays on your device. We use no analytics, advertising or social media trackers, and our fonts are served from our own server.
Your choices and rights
- See and download your data: Account, then Download my data, gives you everything we hold for your account in one file.
- Correct it: change your email or password on your Account page.
- Delete a document: My analyses, then Delete.
- Delete everything: Account, then Delete your account. Your account, documents, analyses and revisions are removed at once.
- Ask us anything, or exercise any other right you have under privacy laws such as the GDPR, the UK GDPR or California’s privacy laws: write to hello@prosemetry.com. We answer within 30 days. You can also complain to your local data protection authority.
Where the GDPR applies, we process your information to provide the service you asked for (contract), to keep the service secure and fair (legitimate interests), to meet legal duties, and, for the update emails, with your consent.
Security
The site uses HTTPS everywhere. Passwords are stored only in hashed form. Each analysis can be opened only by the account or browser that created it. We don’t keep separate backup copies yet. When we add them, deleted information will leave them within 30 days.
Children and students
Prosemetry isn’t meant for children under 13, and we don’t knowingly collect their information. If you believe a child under 13 has used Prosemetry, write to us and we’ll delete it. Students from 13 to 17 should use Prosemetry with a parent’s, guardian’s or school’s permission. Schools that want to use Prosemetry with their students can contact us about an agreement covering student records.
Changes
If we change this policy, we’ll update the date at the top. If a change affects how we use information we already hold, we’ll tell account holders by email before it takes effect.
