Privacy Policy

Last updated: 13 November 2026

1. Controller

The controller of your personal data is DEMY SOLUTIONS LLC, organized in Illinois, USA. Contact: support@capper.win.

2. Data we collect

Account data: your name and email address, and the interface language you choose; if you sign in with Google, your Google account ID and profile avatar.
Favorites: the fixtures you mark as favorite (with their timestamps).
Usage events: when you are signed in, we record a small number of product events linked to your account ID: registering, verifying your email, opening the pricing page, starting or abandoning checkout, and starting or ending a trial or subscription. We also record when you were last active. We use them to understand how the Service is used, not for advertising.
Device preferences: your theme and odds format choices are stored locally in your browser and are not sent to our servers. Your language choice is kept in a cookie (see §4).
Server logs: like most websites, our hosting provider's server logs may briefly record technical data such as IP address and browser type, used only to run and secure the Service. The application itself does not store your IP address.
Payment data: handled by our payment provider (see §5); we never see or store your card details.
Analytics: we use PostHog (PostHog, Inc., USA) to measure how our pages are used. In your browser it runs in cookieless mode: it sets no cookies, keeps no identifier between visits and does not link your visits together. Page views are recorded without your name or email address. We use no advertising trackers.

3. Why we use it (legal bases)

To provide the Service and your account — performance of a contract.
To process payments and prevent fraud — contract / legitimate interests.
To secure, maintain and improve the Service — legitimate interests.
To understand how the Service is used and improve it (analytics) — legitimate interests.
To send service or, with consent, marketing messages — consent / legitimate interests.
To comply with legal obligations (e.g. accounting).

4. Cookies

We use only cookies that are strictly necessary to run the Service or that remember a choice you made about how the site is shown to you:

Session cookie: keeps you signed in.
Security cookie (XSRF-TOKEN): protects forms against cross-site request forgery.
capper_locale: remembers the interface language you chose (1 year).
capper_did: a random identifier set when you start a free-trial checkout, used only to prevent repeated free trials (2 years).
capper_kd: remembers which accounts have signed in on this browser, so that failed sign-in attempts by someone else cannot lock you out (1 year).

We also keep your theme and odds format choices in your browser's local storage and, when the language saved on your account is applied on a new device, a session-only browser-storage entry (capper_locale_adopted) that prevents repeated reloads and is deleted when you close the tab. We do not use analytics, advertising or tracking cookies; our analytics tool runs without cookies (see §2). Because of this, no cookie-consent banner is required. If this changes, we will update this policy and ask for your consent first.

5. Sharing & processors

We share data with service providers acting on our behalf, including:

Payments: Stripe, Inc., which acts as merchant of record for your purchase through its Link checkout service and handles card details, billing data and payment-related support under its own privacy policy. We never receive or store your full card number.
Authentication: Google (if you choose Google sign-in).
Email delivery: Resend (USA), which sends our verification, account and billing emails.
Analytics: PostHog, Inc. (USA); see §2.
Hosting/infrastructure: Hostinger (our servers) and Cloudflare (content delivery and protection against attacks), which process technical request data such as IP addresses.
Internal notifications: Telegram. We send ourselves internal notifications about billing events, such as a new subscription or a cancellation, which include the account's name and email address.

We do not sell your personal data.

6. International transfers

We are a US-based company and some processors may be located outside the EEA/UK. For users in the EEA/UK, such transfers rely on appropriate safeguards (e.g. EU Standard Contractual Clauses).

7. Retention

We keep account data while your account is active and as needed for legal/accounting purposes, then delete or anonymize it.

8. Your rights

Subject to applicable law, you may access, correct, delete, restrict or port your data, object to certain processing, and withdraw consent. California residents have additional rights under the CCPA/CPRA (including the right to know, delete, and opt out of "sale"/"sharing"; we do not sell personal data). To exercise any of these rights, contact support@capper.win. EEA/UK users may also complain to their local data protection supervisory authority.

9. Children

The Service is intended for adults (18+). We do not knowingly collect personal data from anyone under 18. If you believe a minor has provided us data, contact support@capper.win and we will delete it.

10. Changes

We will post updates here with a revised date.
