Signal.
The terms, plainly.
These terms cover your use of Signal, a browser extension that provides context before you choose a public YouTube video. Choose “Agree and continue” in Signal to accept these terms and the data use summarized there. The Privacy and data-use disclosure explains the collection, retention and access controls in detail.
What Signal provides
Signal estimates how well a video delivers on its title and how much of its runtime adds useful detail. Scores and explanations are automated estimates, can be incomplete or wrong, and are not guarantees about a video or its creator. You decide what to watch. Signal may change or be unavailable while we improve it.
Your account and access
Use your verified Google account and keep access to it secure. Do not misuse the service, evade its allowance limits, interfere with other users, or submit unlawful material. Signal may restrict access to protect the service or end separately offered beta access.
The public trial includes 100 successful unique video checks. Eligible waitlist members keep their reserved 250-check trial; existing usage remains counted. Lite is USD 5 per month for 1,500 checks and Standard is USD 10 per month for 4,000 checks. Plus is USD 25 per month for 12,000 checks. Annual billing is USD 50 for Lite, USD 100 for Standard and USD 250 for Plus, charged in full once a year. All paid plans refresh their check allowance monthly, with no rollover. Available billing options are shown at checkout. Paid plans renew at the selected monthly or annual interval until canceled through Stripe’s customer portal; cancellation takes effect according to the period shown there. A separately enabled free-beta Standard activation asks for no card, makes no charge and never converts automatically. Starting a paid subscription always requires a separate choice.
Data used to provide and improve Signal
Signal uses your account identity, public video information, analysis requests, results and allowance use to operate the service. Its public-video processing uses Supadata, OpenRouter and its selected model-serving providers, and a Google Gemini fallback. Google/Firebase handles authentication and Google Cloud hosts the service. The Privacy disclosure explains each recipient, the information it receives and the purpose.
After you accept the in-product data-use agreement, Signal receives account-linked session records: video IDs, score requests and reuse, scores shown, visible opportunities on cards Signal processes, clicks from those cards and explanation opens. These records reconstruct missing, incorrect or late pre-click results: what Signal displayed and whether you clicked before the result or explanation was ready. Signal does not measure playback or watch duration. The same bounded records measure the reliability and displayed-state outcomes of this feature. Request and session diagnostics are retained for 14 days; a bounded offline upload queue may remain in your browser for up to seven days. Existing explicit agreement to the same session data scope remains valid.
Signal does not collect activity from other sites, sell user data, or use it for advertising, lending or credit decisions. Specific support-session inspection requires separate permission when you submit feedback. Other access and use are limited as described in Privacy.
Stopping use and managing data
You can stop using Signal at any time. Signing out stops new account-linked session uploads and clears their pending queue. Disabling or uninstalling the extension stops new collection. These actions do not erase records already accepted by the service. The Privacy disclosure explains retention, account export, erasure and the separate records needed for allowance accounting.
Changes and contact
Material changes to these terms or the agreed data scope will be presented in Signal for review before they take effect for you. Contact Signal support about these terms, your account access or your data. These terms do not limit rights you have under applicable law.
