We collect information in the following ways:
Information you provide: When you sign up for our launch waitlist on the website, we collect your email address. If you later create an account in the App (when that feature is available), we may collect account credentials and any profile or contact details you choose to provide.
Information from the App: The App is designed to work offline-first. Calculator inputs, results, job names, and notes are stored locally on your device. If you enable optional cloud sync, we may store a copy of that data on our servers to sync across your devices. We do not collect or transmit calculator or job data unless you explicitly turn on sync.
Usage and technical data: When you use our website, we may collect technical information such as your IP address, browser type, device type, and general location (e.g. country or region). We use analytics (including PostHog and Vercel Analytics) to understand how the site is used in aggregate—for example, page views and which links or buttons are used (e.g. App Store or Google Play). In the App, we collect minimal usage data (e.g. app version, platform, and anonymised events such as app opens, calculator use, and job creation) via PostHog to improve the product, measure engagement, and optimise marketing. This data is not used to identify you personally unless you have signed in (in which case we may link events to your account to understand usage patterns).
Advertising attribution on iOS: We use Firebase Analytics to measure install and first-open attribution for Google Ads. On iOS, this attribution is enabled only after you grant App Tracking Transparency permission. If you deny permission, we do not enable IDFA-based attribution.
Cookies and similar technologies: Our website may use cookies, local storage, or similar technologies for essential functions (e.g. remembering your theme preference) and for analytics (e.g. PostHog). You can control cookies through your browser settings.
