ColumnFlow is a personal finance app that helps you project monthly cash flow across iPhone, iPad, and Mac. We designed it to keep your data private: your budget lives on your devices and (optionally) in your iCloud account—not on our servers.
Budget data (you enter)
What: months, starting/ending balances, line items (label, amount, date, projected flag), currency code.
Where: stored locally on device and, if iCloud is enabled, in your iCloud private database (CloudKit).
Why: to provide the app’s core functionality (budget projection).
Calendar data (optional)
What: when you use “Add Items to Calendar,” the app creates/updates all-day events in a dedicated “ColumnFlow” calendar with the item’s title and an amount summary in the notes.
Where: saved in your device’s Calendar via EventKit. A small local mapping file (UUID ↔︎ event ID) is stored in the app’s documents folder to keep events in sync.
Why: so projected items can appear on your calendar.
Control: turn off at any time; removing the “Projected” flag or running the update will remove linked events.
Files (optional)
What: CSV import/export of months and items.
Where: handled locally using the system file picker; exported files are saved to a location you choose.
Why: to let you back up, move, or edit data outside the app.
CloudKit notifications
What: the app registers for silent (content-available) remote notifications so CloudKit can nudge the app to pull changes.
Where: delivered by Apple. No marketing notifications.
Why: faster, near-real-time sync.
Control: you can disable notifications in system settings; sync still works, just less instantly.
Diagnostics
In-app log: a lightweight, on-device event list (e.g., “Pushed to CloudKit”).
System crash reports (optional): If you’ve opted in to share diagnostics with developers via Apple, we may receive aggregated crash reports tied to Apple’s identifiers, not to your identity.
You may have rights to access, correct, export, or delete your data. Contact us at lee.manolis@gmail.com for help.
ColumnFlow is not directed to children under 13, and we do not knowingly collect personal information from children.
iCloud is operated by Apple and may store/process data in data centers outside your country. Apple’s safeguards and policies apply to CloudKit storage.
We may update this policy as the app evolves. We’ll change the “Effective date” above and, where appropriate, notify you in-app or on our site.
