Privacy policy
Effective 2026-10-27. Applies to the Access Check add-on for Google Docs™ and Google Slides™ and this website. Operator: SL Studio, Tustin, California (hello@sl-studio.dev).
What the add-on does
Single purpose: check the open Google Doc or Slides presentation for common accessibility issues (alt text, headings, link text, colour contrast, slide titles), show where each one is, and (Pro) fix them from the sidebar.
Google user data the add-on accesses, and why
| Permission (OAuth scope) | Used for |
|---|---|
documents.currentonly | Read the Google Doc the add-on is opened in to run the check; select the paragraph or image of an issue when you click it; and (Pro) write the alt text, heading level or link text you type in the sidebar. No other document or file. |
presentations.currentonly | The same for the Google Slides presentation the add-on is opened in: read it to run the check, select the slide or element of an issue, and (Pro) write the alt text, slide title or link text you type. |
script.container.ui | Show the Access Check sidebar inside Google Docs and Google Slides. |
script.external_request | Check a Pro license key with a11y.sl-studio.dev (key and Google account email only). No other destination is allowed by the add-on manifest. |
userinfo.email | Know which Google account the add-on runs as, so a Pro key can be bound to that account. |
The add-on does not access Gmail, Google Drive files, contacts or any document other than the one it is opened in.
Where the data goes
- Document content stays in Google. Text, images and formatting are read and checked inside Google Apps Script in your own account. They are never sent to us or anyone else. The last check result (issue list with short excerpts) is stored in that document’s own properties; the license cache and the monthly check counter in your account’s user properties.
- License (Pro): when you buy Pro we store your purchase email and the Stripe checkout reference; when you activate, the add-on sends the key and your Google account email to a11y.sl-studio.dev and we store that email as the account the key is bound to. Nothing else.
- Waitlist: if you leave your email on this site we store it to send one launch email, with a confirm and unsubscribe link.
Who we share, transfer or disclose Google user data with
We do not sell, rent or trade Google user data, and we do not share it with advertisers, data brokers or AI model providers. The only Google user data that reaches us is your Google account email at license activation. It is processed by Vercel (hosting of a11y.sl-studio.dev) and stored by Upstash (database). Stripe receives the email you enter at checkout and processes the payment; Resend delivers the license-key email to that address. We may also disclose data if required by law, to protect against fraud or abuse, or as part of a merger or acquisition, in which case this policy continues to apply.
How we protect data
- All traffic between the add-on, our server, Upstash, Stripe and Resend is encrypted in transit with HTTPS/TLS.
- Requests from the add-on are signed with the license key; secrets are kept in our hosting provider’s encrypted settings, never in code.
- Access to production systems is limited to the operator’s accounts, protected by two-step verification.
How long we keep data, and how to delete it
- Document contents: never received, so never retained by us.
- Data in your document’s properties: until you remove the add-on or delete the document.
- License record: kept while the key is valid and for up to 12 months after, for support and accounting, then deleted.
- To delete any data linked to your email or Google account, write to hello@sl-studio.dev. We delete it within 30 days and confirm by email. Removing the add-on and revoking access at myaccount.google.com/permissions stops all further access immediately.
Limited Use
Access Check’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We use document data only to run the check and the fixes you asked for, inside your account. We do not sell it, use it for advertising, use it to train AI models, or let humans read it.
