Privacy Policy
This Privacy Policy explains what data TypoSweep collects, how we use it, and what we don't do with it.
What we collect
- Your email address, which you provide on the upload form. We use it to send you your preview, your completed TypoSweep, and occasional service-related messages.
- Your manuscript file, which you upload. We process it through our typo-detection pipeline; that's the entire purpose we have for it.
- Payment metadata (whether you paid, when, for how much) is stored by Stripe. We see only what Stripe shows us in our dashboard, never your actual card details.
- Basic usage data (your IP address and timestamp of upload) is recorded so we can enforce daily rate limits on the free preview and diagnose abuse.
What we don't do with your manuscript
- We do not use your manuscript to train AI models, and neither does Anthropic, whose Claude API performs the proofreading. Anthropic's commercial API terms prohibit training on inputs.
- We do not sell, share, or license your manuscript. We don't read it ourselves, and no provider uses it for anything beyond delivering your TypoSweep. No marketing partner sees it.
- We do not advertise based on its contents.
How long we keep it
We delete every uploaded manuscript and every generated TypoSweep file from our storage 30 days after upload. You can also delete your files yourself anytime via the "Delete from our servers" button on your job page. After deletion (yours or ours), the only record we retain is the metadata (your email, payment status, word count, flag counts) used for accounting and support.
The download links we email you keep working for the full 30-day window, after which the files are deleted and the links stop working. We still recommend saving the files to your own computer once they arrive. If you've lost the email but it's still within that window, you can return to your job page and download again from there.
How Anthropic handles your text
Your manuscript is sent to Anthropic's Claude API to perform the proofreading. Under Anthropic's commercial API terms, your text is never used to train any AI model. Anthropic deletes it within 30 days, and never uses it for training. We do not read your manuscript ourselves, and no other provider receives it. For more, see Anthropic's policy on data and model training.
Where it lives while we have it
Manuscripts and generated reports are stored encrypted at rest in Cloudflare R2 object storage. They travel over TLS-encrypted connections in transit. Database records (your email, job metadata) live in a managed Postgres database.
Who we share with
We use a small number of service providers, each for a single function:
- Anthropic. Runs the Claude AI model that performs the TypoSweep.
- Stripe. Processes payments.
- Cloudflare. DNS, hosting (R2 storage), bot protection.
- Render. Application hosting.
- Resend. Sends transactional email.
- Sentry. Captures application errors so we can diagnose and fix bugs.
- Google. Provides analytics (Google Analytics 4) so we can understand how visitors find and use the site. Does not see your manuscript.
Each of these providers sees only what it needs to do its job. Stripe sees your email and payment. Resend sees the email we send to you. Anthropic receives your manuscript text to perform the proofreading; see “How Anthropic handles your text” above for retention detail. No other provider sees your manuscript.
Your rights
You can ask us to delete your data at any time by emailing hello@typosweep.com. We'll honor the request within 14 days.
Children
TypoSweep is intended for adults. We don't knowingly process data from anyone under 16.
Changes
If we materially change this Policy, we'll update the date above and, for changes affecting existing customers, send an email notification.
