CARBON by Testers.ai
Privacy & data handling
Updated September 19, 2026. This notice covers the CARBON homepage and its Cloud/Local entry points. The separate legacy chat privacy policy applies to the older chat experience, not to every CARBON workflow.
Browsing this homepage
The coffee-shop and coding-agent animations are illustrations. They do not submit a URL, order anything, or run tests. Profile dialogs work locally in your browser.
The homepage loads Fathom Analytics for site-usage measurement. It also keeps limited campaign attribution in browser local storage when a supported campaign code is present: utm_source, utm_medium, and utm_campaign, plus a first-seen timestamp. Only short letters/numbers/hyphens/underscores are accepted. Please do not put personal information in campaign codes.
This updated homepage and Cloud entry page do not retain full landing URLs, referrer URLs, search text, ad click identifiers, or arbitrary query parameters in that record. Attribution expires after 30 days and is removed on the next visit or submission; old-format records are discarded when either updated page loads. Other legacy pages may use older attribution code. Browser site-data controls let you remove local records sooner.
Using CARBON Cloud
When you submit the steering form, your target URL, email address, and optional context are sent to the Testers.ai cloud service to prepare a test plan. Uploaded specifications and custom tests are also sent when included. Running a plan requires cloud access to your target; captured page content, screenshots, requests, and results may contain information visible in the tested application. AI processing depends on the chosen cloud configuration and providers.
Use synthetic accounts and data. Only submit targets you are authorized to test. Do not paste passwords, private keys, or sensitive customer records into ordinary notes. Check the run’s visibility setting before execution and before sharing a report. A publicly shared report can be read by others; local browser storage is not an access-control boundary.
Cloud plan details currently advertise 30-day report retention. Account records, support correspondence, operational logs, backups, and connected AI-provider handling are separate from that report window. For requirements about exact deletion, data location, provider processing, or contractual retention, contact hello@testers.ai before sending sensitive material. Clearing your browser does not delete cloud reports.
Using the Local Harness
The harness runs in your coding agent and saves project artifacts locally. “Local” does not mean that your coding-agent provider processes no data: its own account, model, tool, and privacy settings apply. Optional cloud testing and integrations send the selected inputs to the configured service. Review those settings before enabling them.
Contact requests
When you ask to talk with us, we collect your name, email, company, role, product and plan interest, intended use, desired outcome, and problems to solve. These answers are stored in a private Testers.ai Google Sheet and sent by email to jason@testers.ai so we can respond. A request does not create an account, start a subscription, or subscribe you to marketing emails. Contact jason@testers.ai to ask about or delete your inquiry. Please do not submit passwords or confidential customer data. The form does not save your answers to browser storage or send them to Fathom.
Accounts, billing, and choices
Cloud account and billing actions open Testers.ai services and may continue to Stripe. These services process the account or payment information you submit. Local account/session information can remain in your browser until you sign out or clear the relevant site data.
For access, correction, deletion, or privacy questions, email hello@testers.ai with the relevant account email or report identifier. Do not email passwords or API keys. Fathom’s privacy notice explains its analytics service.
