Privacy Policy
1. Scope and provider
This policy covers the CashTide (潮汐) app and this legal website. The app is provided by the developer identified on its App Store product page. Contact [email protected] with privacy questions.
2. Your cash-flow data
Balances, safety thresholds, projects, income and expense rules, amounts, dates and enabled states are used to calculate and display forecasts on your device. They are stored locally. The current version requires no app account, does not connect to bank accounts and does not upload this cash-flow data to developer servers. Currency preferences and cached membership status are also stored on your device.
3. Purchases and membership
Apple App Store and StoreKit handle Pro purchases and restoration. The app uses transaction and entitlement information supplied by Apple to determine your plan, expiration and renewal status. The developer does not receive your full payment-card details. Apple’s privacy policy applies to its processing of account, payment and related data.
4. Backups, sharing and system services
When you export a backup, it contains balances, safety thresholds, projects and rules. A storage provider or recipient you select through the system share sheet or file picker may receive that file; keep it secure. Backup imports are processed locally. iOS device backups and Apple diagnostics depend on your system settings and Apple’s policies. The app does not offer developer-operated cloud sync.
5. Advertising, analytics and permissions
The current version includes no advertising, third-party behavioral analytics or cross-app tracking SDKs, and does not sell cash-flow data. Basic forecasting does not require access to contacts, location, microphone or photos. System file import and sharing are used only when you initiate them.
6. Website and support
When you visit this website, your browser sends IP address, request path, time and browser-related information to the web server and network providers, including Cloudflare, for page delivery and security. The legal website contains no advertising, analytics scripts or application-level tracking cookies. Routine access logging is disabled at the origin; network providers may still process security logs under their own policies. If you email support, we process your email address and message to respond and resolve the issue. Do not send unnecessary financial details.
7. Retention, deletion and control
Local data remains until you edit it, clear it or delete the app. “Clear all cash flows” in Settings removes projects and rules but keeps your current balance and safety threshold, which you can edit separately. Deleting the app normally removes its local data; exported files, system backups and Apple purchase records must be managed separately. Support messages are retained for handling your request and necessary follow-up, unless retention is required by law. You may contact support to request access, correction or deletion of support information held by the developer.
8. Security and minors
We minimize data processing, rely on system storage protection and serve legal pages over HTTPS. No storage or transmission method is completely secure; protect your device and backups. We do not actively collect personal profiles from minors through the app. Minors should obtain appropriate guidance and permission from a parent or guardian when using or purchasing the app.
9. Policy changes
We will update this policy and its date when our data practices change, and provide notice or obtain consent where required by law. Descriptions of the current version do not authorize undisclosed future data processing.
