FAQ

General

How accurate is the analysis?

Themys uses large language models (LLMs) to analyze Terms of Service text. The analysis is generally reliable for identifying common concerns like data sharing, arbitration clauses, and liability limitations.

However:

• The analysis is not legal advice. It's a tool to help you understand what you're agreeing to.
• Accuracy depends on the quality of the source text. Extracting from clean HTML pages produces the best results.
• LLMs may occasionally miss nuance or flag clauses that are standard for a specific industry.
• Laws vary by jurisdiction. A clause flagged as problematic in one country may be standard in another.

For high-stakes decisions, always consult a qualified attorney.

Is my data private?

Yes. Your scan data is stored per-user and is not shared with other users or third parties.

• Each scan result is tied to your account
• Scan history is only visible to you when logged in
• The extracted ToS text and analysis results are stored securely
• Themys does not sell or share your scan data

You can delete your account and all associated data at any time from Settings > Delete Account.

What permissions does the Chrome extension need?

The extension requests four permissions:

PermissionWhy ----------------- activeTabReads the current tab to extract Terms of Service text. Only accesses the page you're viewing. storageSaves your login token locally so you stay signed in. tabsCommunicates between the popup and the page content script. alarmsKeeps the service worker alive on Manifest V3.

The extension does not access your browsing history, bookmarks, or tabs you aren't actively using.

Can I use Themys without the extension?

Yes. The web app at themys.ca/scan/new provides the same analysis features:

1. Go to the scan page

2. Paste the URL of any Terms of Service

3. Click Analyze

No browser extension required. The web app works in any modern browser.

Scans & Limits

How do credits work?

Credits are used when you exceed your daily scan limit:

• Free plan: 5 scans/day, no credits
• Base plan: 25 scans/day
• Advanced plan: 100 scans/day

When you hit your daily limit, each additional scan consumes 1 credit. Credits roll over month to month and don't expire.

You can purchase additional credit packs from Settings > Credits:

PackCreditsPrice ---------------------- 10 credits10$1.99 50 credits50$7.99 200 credits200$24.99

What happens when my daily limit resets?

Daily scan limits reset at midnight UTC every day. After the reset, you get your full daily allowance back regardless of how many scans you used the previous day.

Credits are independent of the daily limit. They carry over and are only used after the daily limit is exhausted.

Can I export my scan results?

Export functionality is coming soon. In the meantime, you can access your scan results programmatically through the API.

Can Themys scan any website?

Themys works best on pages that contain Terms of Service, Privacy Policies, or similar legal documents. It can extract text from:

• Standard HTML pages
• JavaScript-rendered pages (via Jina Reader API)

It may not work well with:

• Pages that require authentication to view
• Pages with heavy anti-bot protection
• Dynamically loaded content behind user interaction

API

Is there an API?

Yes. Themys provides a REST API for extracting and analyzing Terms of Service programmatically.

See the API documentation for details:

• API Overview: Authentication, base URL, and general usage
• POST /api/extract: Extract text from a URL
• POST /api/analyze: Analyze text and get risk scores

How do I authenticate with the API?

All API requests use a Bearer token from your Clerk session. See the API Overview for details.

What are the API rate limits?

Billing

How does billing work?

Subscriptions are managed through Stripe. You're billed monthly on the date you subscribed.

• Upgrade: Takes effect immediately with prorated billing
• Downgrade: Takes effect at the end of the current billing cycle
• Cancel: Your plan reverts to Free at the end of the billing cycle

Can I get a refund?

Refund requests are handled on a case-by-case basis. Contact support at support@themys.ca with your account email and the reason for the refund request.

Credit pack purchases are generally non-refundable once credits have been used.

What happens to my data if I downgrade?

Your scan history is preserved when you downgrade. You just get fewer daily scans:

• Previously completed scans remain in your history
• Existing credits carry over
• Daily scan limit changes to match the new plan

Troubleshooting

The extension isn't detecting ToS pages

1. Make sure the extension is enabled at chrome://extensions

2. Verify the page actually contains Terms of Service content

3. Try clicking the extension icon to manually trigger a scan

4. Check if the page requires authentication

5. Reload the page and try again

My scan failed with an error

Common causes:

• "Extraction failed": The page blocked automated access or returned no readable text. Try the web app instead.
• "Daily scan limit reached": You've hit your daily scan limit. Wait for the midnight UTC reset or use credits.
• "Text too short": The extracted text was under 50 words. Verify the URL points to the actual ToS page.
