Privacy, in plain language.
What Strut stores, why it stores it, how long it keeps it, and how to get it all back.
Last updated:
- Your writing is yours. Only you and the people you invite can read it.
- We never sell your data and we do not run advertising.
- We store what the product needs to work: your projects, notes, drafts, and how much AI you have used.
- You can leave with everything. Export any document, delete any project, or email us to remove your account.
What Strut stores
If you only read the guides
You can read every page in the field guide without an account. We do not ask for your name or email to do that.
If you create an account
You sign in with Google, so we receive the name and email on that Google account. From then on we store the work you make:
- Projects, documents, notes, and every saved version of a draft
- Comments, collaborator settings, and any review links you create
- Imported source files, voice samples, generated images, and narration audio
- How much of your AI allowance you have used, and how many words you added each day (this is what draws the streak and activity graph on your dashboard)
Strut has no password to store. Google verifies who you are, so there is no Strut password to lose or leak.
What stays on your own device
The workspace demo keeps its sample notes in your browser and never sends them anywhere. The real editor also keeps two small things locally: a backup of unsaved changes until they reach the server, and preferences such as your chosen reading voice. Clearing this site's browser storage removes all of it.
How your writing is processed
When AI runs on your text
Some features send text to a contracted third-party AI processing service. This happens only when you ask for it, and only with the material that request needs. Those features are:
- Writing operations such as expand, outline, strengthen, and critique
- Questions asked of an imported source
- Scanned-page text recognition (OCR)
- Voice-note transcription and Voice Profile analysis
- AI images and audio narration
Everything else runs without sending your text anywhere. Editing, search, version history, collaboration, and exports all keep working when your AI allowance runs out.
Your AI allowance
| Plan | AI allowance | Resets? |
|---|---|---|
| Free | 2,000 AI tokens each day you open your dashboard, up to 50,000 in total | Collected daily, to a lifetime maximum |
| Pro | 1,000,000 tokens | Yes — every calendar month |
Strut holds back a small, conservative amount before each AI action so an operation cannot overspend the balance. Full details are on the pricing page.
Files, storage, and how long we keep things
Where files live
Imported sources, audio notes, generated images, and narration audio are stored privately, either on our own server or in a private S3-compatible bucket. Every download is permission checked, so a file cannot be reached by someone who is not on the project.
How long things are kept
| What | How long |
|---|---|
| Manuscripts, documents, notes, versions | Until you delete them |
| Imported source files (free plan) | 30 days of inactivity — opening a source resets the clock |
| Uploaded audio after transcription | Deleted after its short processing window |
| A project you delete | Removed with its notes, documents, versions, comments, sources, and generated files |
Sharing and collaboration
Review snapshots
You can publish a frozen, read-only copy of a document at a hard-to-guess link. It is a snapshot, so later edits never appear unless you deliberately refresh it. You can add a password, set an expiry, or revoke the link at any time. A review password does not create an account for the reader.
Collaborators
People you invite as an editor or reviewer can see that project. The project owner can remove that access whenever they choose. Read more about how this works on the collaboration page.
Accounts, billing, and email
Signing in
Google sign-in is the only way into a Strut account. After Google confirms who you are, we set a session cookie to keep you signed in.
Payments
Stripe collects and stores payment details. We never see or store your card number. Strut receives only your subscription status and a customer identifier, and grants Pro access after Stripe confirms an active subscription or card-verified trial.
Activity emails
If you wrote something during the past week, we may email you a short summary of your word total and writing days. Reply to any summary and we will stop sending it.
Operational data
Like any web service, our security and reliability logs record IP address, browser information, the page requested, timestamps, and errors. We use this to keep the service running, enforce plan limits, investigate abuse, and fix problems. We do not use it to build advertising profiles.
Your choices
You are never locked in. At any time you can:
- Export any document as PDF, Word, Markdown, or plain text
- Delete a whole project, including everything inside it
- Remove a single imported source file
- Revoke a review link or a collaborator's access
- Email us at [email protected] to access, correct, export, or delete your account data
Common questions
Do you sell my data or run ads?
+
No to both. Strut is funded by subscriptions, which is the whole reason we can say this plainly.
Is my writing used to train AI models?
+
No. Your text is sent to a processing service only to complete the specific operation you requested, and it is not used to train models.
Can my collaborators see my other projects?
+
No. Access is granted per project. Someone invited to one manuscript cannot see anything else in your workspace.
How do I delete everything?
+
Delete each project from your dashboard, which removes its notes, documents, versions, sources, and generated files. For full account removal, email [email protected].
