Privacy Policy

Data we handle

The core calculators run in your browser. Values entered into a calculator are not stored in our database unless you sign in and explicitly use a feature that saves data. We process data only as needed for accounts, saved characters, party matching, realtime collaboration, and advertising.

Cookies and advertising

Necessary cookies maintain signed-in sessions. Light or dark theme preference is stored in your browser's localStorage and is not sent to our server. Third-party advertising services, including Google AdSense, may use cookies or similar technologies to serve, measure, and personalize ads based on visits to this and other websites.

You can manage personalized advertising through Google Ads Settings or opt out of some third-party advertising cookies at aboutads.info.

Accounts and saved data

We use Cloudflare D1 for authentication and data storage. If you choose to sign in, we store your email address, a one-way password hash, basic account metadata, characters you explicitly save, and party-lobby membership data. Cloudflare Email Sending processes account confirmation and password-recovery emails.

Party and member information is visible to other signed-in players as needed for matching. We do not sell this information. You may request deletion of your account and related data at any time.

Realtime collaboration

The Romeo and Juliet collaboration tool uses Cloudflare Durable Objects and WebSockets to sync room codes, presence, and platform markers. The latest room state may be stored temporarily for up to six hours so players who join later can continue the session; it is not added to the account database. Anyone who knows a room code may join that room, so do not include personal data in a room code or marker.

Analytics

We use Ahrefs Web Analytics for aggregate page, referrer, device, language, and approximate-region reporting. It is cookie-free by default and does not retain raw IP addresses. Calculator inputs and account identifiers are not intentionally sent to Ahrefs.

Your choices and rights

You may ask to access, correct, or delete personal data we hold about you. You may also block or delete cookies in your browser, although doing so can affect some site features.

Updates and contact

We may update this policy from time to time. Material changes will be reflected on this page. For questions or privacy requests, email contact@archie-design.app.
