Privacy Policy

Do Not Sell or Share

Effective November 15, 2026

Polytropa LLC ("Polytropa", "we", "us") makes web apps for small and mid-sized businesses in the United States and sells them under the Polytropa name. This policy explains what personal information we collect on polytropa.com, on our early-access pages and in our apps, why we collect it, who helps us process it, how long we keep it and what choices you have.

Who we are

Polytropa LLC, 2232 Dell Range Blvd, Suite 303 PMB 2027, Cheyenne, WY 82009. You can reach us at [email protected].

What we collect

• Early-access sign-ups. When you join an app's early-access list we collect your email address, the app you asked about, the page you signed up on and the ad that brought you there.
• Accounts. When you create an account in an app we collect your email address, your sign-in details, and your name and your business's name if you give them.
• What you put into an app. The records, files and text that you and your team enter. This is your business's data. We use it only to run the app for you.
• Payments. Stripe collects your card details on its own pages. We never see or store full card numbers. We receive your billing name, postal code and country, the card's brand and last four digits, and the status of each payment.
• Messages. Emails you send us, voicemail you leave on our phone line, and our replies.
• Usage and device data. The pages you visit and the actions you take on our sites and in our apps, the time, your browser and device type, your IP address, and error reports.

How we use it

We use personal information to:

• run our sites and apps and keep them secure;
• tell people on an early-access list whether the app launches;
• bill subscriptions and send receipts, renewal notices and other service messages;
• answer support messages;
• count, in totals, which ads and pages bring visitors and sign-ups;
• meet our legal, tax and accounting duties.

We do not sell personal information, and we do not build advertising profiles of people.

Advertising

We advertise on TikTok. When you arrive from a TikTok ad, we keep the click ID TikTok adds to the link, together with the campaign and the ad it names, so that we can count the visitors and sign-ups each ad brought. We send no tracking pixel, conversion data or customer data to TikTok, and we place no advertising cookies on our pages.

Sign-up screening

To keep bots out of early-access lists, we keep the IP address used for each sign-up. We delete that IP address 30 days after we decide whether to build the app.

AI services

We use AI services from xAI and Anthropic to run our products and to answer support messages. Text you enter into an AI feature of an app, and support messages you send us, go to these providers so that they can produce the answer. They process it on our behalf.

Who processes it for us

We use these service providers to run our sites and apps. Each receives only what it needs for its job:

• xAI: AI models for app features and support replies
• Anthropic: AI review of our apps and pages
• Stripe: payments and billing
• Render: hosting our apps and websites
• Supabase: databases
• Cloudflare: domain names, email routing and file storage
• Resend: sending email
• PostHog: product analytics
• Sentry: error monitoring
• Twilio: our phone line

We also disclose personal information when the law requires it, when it is needed to protect our rights or someone's safety, and to a buyer if we ever sell the business or one of our apps. In that last case we tell the people affected first.

How long we keep it

• App data: for as long as you have access to the app, and for 60 days after your access ends. Then we delete it.
• Billing records and our accounting books: 7 years.
• Early-access sign-ups: while you stay on the list. If we decide not to build an app, we tell you once by email and delete your sign-up 30 days later, unless you asked to hear about our other apps.
• Support messages: 18 months.
• Records of consent and of opt-outs: 3 years.
• Server and security logs: 90 days.

Your choices and your rights

• Marketing email. Every marketing email has an unsubscribe link, and we honor it at once. Receipts, renewal notices and security messages still reach you while you have an account.
• Your information. You can ask us for a copy of the personal information we hold about you, ask us to correct it, or ask us to delete it. Write to [email protected] from the email address we have for you. We answer within 30 days.
• Your app data. You can export your data from an app at any time while you have access.
• State privacy laws. Some US states give their residents these and further rights, including the right not to be treated differently for using them. We honor these rights for everyone we serve, whichever state you live in.

Do Not Sell or Share My Personal Information

We do not sell your personal information, and we do not share it for cross-context behavioral advertising. If you have a question or a request about this, write to [email protected].

Cookies and analytics

Our apps use cookies that are needed to keep you signed in. We use PostHog to count visits and to see how our pages and apps are used, and Sentry to find errors. We use no advertising cookies and no advertising pixels.

Security

We encrypt data in transit, limit who and what can reach it, and keep backups. No system is perfectly secure. If a breach affects your personal information, we will tell you as the law requires.

Children

Our apps are made for businesses. They are not directed to children, and we do not knowingly collect personal information from anyone under 16.

Where we operate

We serve customers in the United States, and we process personal information in the United States.

Changes to this policy

When we change this policy we post the new version here and change the date at the top. If a change is significant, we also email account holders before it takes effect.
