Your text

The style scanner runs in your browser. Rewriting sends your text to our Cloudflare Worker and Cloudflare Workers AI to generate a paraphrase. Our application does not save submitted text or rewritten output to a database, and application request logging is disabled. Text remains visible in the page until you clear it or leave; copying or downloading it saves it where you choose.

Cloudflare processes requests as our hosting and AI provider. Its own service terms and privacy practices apply to that processing. Advertising code is not given the contents of the text boxes or rewrite API responses by this application.

Accounts, subscriptions, and support

If you sign in, Supabase processes your email address and authentication information. Resend delivers sign-in and account-confirmation emails and processes the recipient address and email message for delivery. Its open and click tracking are not enabled for our authentication emails. Supabase's browser library stores your sign-in session in local storage so you can stay signed in; signing out clears that session. Our server verifies your identity with Supabase.

Stripe handles checkout, payment details, subscriptions, invoices, and the billing portal. We do not receive or store your full payment-card number. Our membership database stores your account identifier, Stripe customer and subscription identifiers, subscription status, and access expiry. Billing event identifiers are retained for duplicate-event protection and pruned after 30 days.

Account and billing records support membership access, payment management, and applicable record-keeping obligations. Provider retention periods can differ. If you contact support, your email and the information you include are used to respond to the request.

Daily limits and hosting

Cloudflare receives network and request information, including IP addresses, to deliver and protect the service. For our free-use counter, the application hashes the network IP together with the current UTC date. It stores that daily identifier and a count rather than the raw IP or your text. Old daily counts are pruned after two days. People using the same network share the free allowance.

Advertising and advertising cookies

Google AdSense is being configured and is subject to Google's approval. The site does not show paid members ads. When advertising is active, Google and other advertising vendors may use cookies, local storage, IP addresses, device information, and information about visits to this and other websites to deliver, personalize, measure, and protect advertising. These vendors may infer an approximate location from network information.

Google's advertising cookies can help it and its partners show ads based on previous visits across websites. See how Google uses information from partner sites and Google's advertising technology providers.

Where applicable, a consent message lets you consent, refuse, or manage advertising choices before eligible ad requests. You can revisit available choices using the privacy controls shown on this site. You can also adjust Google's personalized advertising in My Ad Center or explore participating vendors' choices at YourAdChoices. These settings may not remove all advertising. Browser controls can delete or block cookies and local storage, which can also affect sign-in.

Service providers and international processing

Hosting, authentication, payment, and advertising providers may process data in countries other than your own. Read their privacy information: Cloudflare, Supabase, Resend, Stripe, and Google.

Depending on where you live, you may have rights concerning access, correction, deletion, or objection to certain uses of personal information. Contact spades@istusa.net with your request. We may need to verify account ownership before changing or disclosing account records. Some information may need to be retained for payment or legal obligations.
