Privacy notice

ProfitStamp Privacy Notice

Who we are: ProfitStamp LLC, a Wyoming limited liability company (“ProfitStamp”, “we”), 30 N Gould St Ste N, Sheridan, WY 82801, USA. Contact: [email protected].

The short version: we only get the order details the store passes to us when you buy, the email address you give us for the free Profit Calculator or our newsletter, and whatever you email us. We never see your spreadsheet data.

What we receive

• From the store you bought from (Gumroad or Polar): your name, email address, what you bought, and when. Stores don’t share your payment card details with us.
• From you: anything you include in emails to [email protected], including feedback you send as a pilot tester.
• If you get the free Profit Calculator or sign up for fee-change notices on our website: your email address (see “Website” below).

What we never receive

• Your spreadsheet data. Your copy lives in your own Google account. We have no access to it. The spreadsheet has no scripts or add-ons and sends nothing anywhere.
• Your marketplace passwords or bank details. We will never ask for them.

Why we use it, and the legal basis

• To deliver your purchase and answer support: this is part of the sale you agreed to (legal basis: performing our contract with you).
• To send fee-update notices and fixes for your version: also part of the sale (performing our contract with you).
• To send you the free Profit Calculator’s copy link and its fee-change notices for 6 months: you asked for it when you signed up (legal basis: your consent). Unsubscribing stops the notices; your copy keeps working.
• To send you one email when the next edition launches, with its discount: we have a reasonable business interest in telling past customers (legal basis: legitimate interest). Reply to [email protected] to opt out.
• To send the fee-change newsletter and launch news, and to run a pilot test you agreed to join: you asked for it (legal basis: your consent). You can withdraw your consent at any time.
• To keep order records: we are legally required to keep business and tax records (legal basis: legal duty).
• To block abuse of our website’s signup form: we need it to keep working (legal basis: legitimate interest).

If you don’t give us an email address we can’t deliver your purchase or the free Calculator, or answer you; everything else is optional. We don’t make automated decisions about you and we don’t build profiles.

Who else handles it

• The store you bought from (Gumroad or Polar). It runs checkout as the seller of record and handles your order data under its own privacy policy.
• Microsoft 365, which we buy through GoDaddy, hosts [email protected].
• Kit (formerly ConvertKit) sends the free Calculator’s signup emails, the fee-change newsletter and launch news.
• Cloudflare hosts the website and counts visits.

These providers handle your data only on our behalf, under their own data-protection terms. We don’t sell your personal information, share it for advertising, or use it to advertise to you.

Where it’s handled: mainly in the United States. If you’re in the EU, the UK or Switzerland, your data is sent to the US under legal transfer protections: the EU-U.S. Data Privacy Framework (with its UK and Swiss extensions) or standard contractual clauses, which are contract terms approved by regulators.

How long we keep it

• Support emails and pilot feedback: 12 months after your last message.
• Order records: 7 years, for business and tax records.
• Newsletter: until you unsubscribe, after which we stop emailing you. To have your address erased from the newsletter service too, email us.
• Website abuse counter: 1 hour.

Your rights: you can ask us to show you what we hold about you, give you a copy, correct it or delete it. You can also ask us to limit how we use it, object to a use, or withdraw your consent. Email [email protected] from the address we hold for you. It’s free, and we reply within 30 days. For order data the store keeps, ask the store; its policy applies. If you’re in the EU or the UK, you can also complain to your data protection authority. If you live in a US state with its own privacy law, you have these rights too.

Children: our products are for businesses and are not directed at children under 16.

Website (profitstamp.com)

• The site is static pages, with no cookies, accounts or advertising trackers.
• Analytics: Cloudflare Web Analytics counts page views, referrers and page-speed measurements without cookies and without fingerprinting visitors.
• Newsletter: if you sign up for fee-change notices, we send your email address to Kit, which emails you to confirm (double opt-in) and records when you confirm. Every email has an unsubscribe link. To stop abuse, our signup form keeps a scrambled (hashed) count per IP address for 1 hour; we don’t store your IP address itself. For buyers the newsletter is optional: they get update notices through the store they bought from either way. For the free Profit Calculator, the signup is how the copy link and the notices reach you.
• Hosting: the site is served by Cloudflare, which processes visitor IP addresses to deliver pages and block abuse.
• Checkout happens on the store’s site (Gumroad or Polar), under that store’s privacy policy. We never see card details.

Changes: if this notice changes, the new version will show an updated date. Last updated: October 31, 2026
