SpinDone is developed and published by Basalt Works. This page explains what information the app may use, how it is handled, and what rights users have.
Last updated: September 2, 2026
This Privacy Policy explains how Basalt Works ("we," "us," or "our") collects, uses, discloses, and protects your personal information when you use the SpinDone mobile application (the "App").
This policy applies to users worldwide. Privacy rights and our obligations may differ depending on where you live, including under the GDPR in the European Economic Area and the CCPA/CPRA in California.
Basalt Works is responsible for the information it receives and controls as described here. RevenueCat, Apple, Google, Formspree, and Vercel also process information under their own roles and privacy terms.
SpinDone is local-first. The App stores activities, plans, templates, settings, history, and statistics on your device using AsyncStorage. Basalt Works does not operate a backend that receives this core planning data, and the App does not include a product analytics service.
The export feature creates a local JSON file that you can save to your device or share through your device's sharing options. A copy you export or share is controlled by you and the service or recipient you select.
RevenueCat is active in SpinDone and initializes when the App launches. It uses an anonymous app-user identity to retrieve available products and customer entitlement status and to process purchases and restores with the Apple App Store or Google Play. RevenueCat and the relevant store may process purchase and restore information, transaction or receipt data, and entitlement status. Basalt Works does not receive or store your payment card details.
If you grant notification permission and choose a reminder, the App schedules it locally on your device after your action. SpinDone does not register a remote push token or use a push-notification backend for reminders or updates.
If you grant calendar permission and choose to export an activity, the App writes that activity's title and times to the system calendar you select. Those details then become part of the selected calendar and are handled under its settings and provider terms.
SpinDone currently has no ads and contains no product analytics or crash-reporting SDK. The App does not request App Tracking Transparency permission and does not use active Expo over-the-air updates.
Apple and Google may provide crash reports and technical diagnostics through App Store Connect and Google Play Console according to their platform policies and device settings. These reports can include app, device, and operating system data, but not activities, plans, or other planning content stored locally in SpinDone.
If you contact support by email, we receive the information you choose to include. The website support form sends your email address, issue type and message, plus any optional device model, operating system version and app version you enter. It also sends the app name and source page. Formspree processes these submissions so we can receive and answer your request.
When you select English or Spanish on Basalt Works product or support pages, the website stores that preference in your browser's localStorage under basalt-lang. If no preference is stored, the website reads your browser language and uses Spanish when it begins with "es"; otherwise it uses English. This storage is used only to remember the display language and remains until you change it or clear the website's local storage.
These pages are hosted on Vercel. Its infrastructure may process request metadata needed to serve and protect the pages, such as IP address, request date and time, requested URL, request headers, and browser or device information.
For users in the European Union, we process personal data based on the following legal grounds:
SpinDone automatically prunes detailed daily history after 30 days and per-day activity statistics after 365 days. Aggregate and lifetime statistics, along with other local planning data, remain until you reset them, clear the App's storage, or uninstall the App, subject to device backup and restore behavior.
The in-App Delete Data action clears the core data it identifies, but it does not erase every auxiliary local key. It also cannot delete purchase records held by Apple, Google, or RevenueCat, calendar events already written to your calendar, or copies you previously exported or shared. Those records or copies must be managed with the relevant store, provider, calendar, app, recipient, or device control.
SpinDone does not configure a fixed retention period for store or RevenueCat records. Those providers retain information under their own legal obligations and policies. Support messages are kept only as long as reasonably needed to respond and maintain support records.
Depending on the law that applies and subject to its conditions and exceptions, you may have the following rights for personal information Basalt Works controls:
California residents may have the following rights, subject to applicable definitions and exceptions:
Basalt Works does not sell personal information for money. SpinDone currently contains no ads, and we do not use information from the App for cross-context behavioral or targeted advertising.
We disclose limited information to RevenueCat and Apple or Google to provide purchases and restores, and to Formspree or Vercel when you use the support website. These providers may process information under their own terms. Contact us if you have a request under a law that treats a disclosure as a "sale" or "sharing."
The App and its product and support pages use the following third-party services:
The App is not intended for children under the age of 13.
We do not knowingly collect personal information from children under 13. If we become aware of such collection, we will take steps to delete that information promptly.
We implement appropriate technical measures to protect your information. However, no method of electronic storage is 100% secure, and we cannot guarantee absolute security.
RevenueCat, Apple, Google, Formspree, and Vercel may process information in countries other than where you live. Privacy protections in those countries may differ.
Where transfer safeguards are required, processing is subject to the mechanisms and contractual terms made available by the relevant provider and applicable law. Contact us if you want more information about a transfer related to data Basalt Works controls.
We may update this policy periodically. We will notify you of changes by posting the new policy in the App and updating the "Last Updated" date.
