Snowball Flow
Privacy Policy
Last updated: October 1, 2026 · Snowball Flow for Android
1 Who We Are
Snowball Flow ("the App") is a debt snowball planner and job income tracker, operated by Swap Widget LLC ("we"). If you have any questions about this policy, email swapwidget@gmail.com.
2 Your Data Stays on Your Device
Your debts (names, lenders, balances, interest rates, minimum payments, due days and escrow), the payments you check off, statement balances, your payoff plan and settings, jobs and income, expenses and notes are stored in the App's private storage on your phone.
The App has no sign-in and no cloud sync of its own, and none of this information is ever sent to us. The only time the App connects to the internet is on the Support & feedback page (section 6), and what goes out there is only what you type into a message.
3 Data We Do NOT Collect
4 Importing Spreadsheets
When you import, you pick a file with your phone's file picker, or copy cells in a spreadsheet app and tap Paste. Snowball Flow reads the file or the copied cells on your phone and saves what you confirm. Nothing is uploaded. The App reads your clipboard only at the moment you tap Paste.
5 Backups Are Files You Control
Export and restore. More › Back up to a file saves all your data as one file, and More › Export to CSV makes spreadsheets of your jobs, expenses, payments or payoff schedule. You choose where they go, such as your phone's storage, a cloud drive or an email. We never receive them. If you save it to a cloud service, that service's privacy policy applies to the copy. Restore reads a backup file only when you pick it.
Automatic safety copies. The App keeps a few recent copies of your data inside its own storage on your phone (the latest, one per day for two weeks, and one before big changes such as an import), so a mistake can be undone. They never leave your phone on their own.
Your phone's backup. Android's own backup may copy the App's data, including those safety copies, to your Google account, and carries it to a new phone when you set one up. When your phone has a screen lock, Android encrypts that backup end to end. You control it in your phone's settings.
6 Support Messages You Send
Only when you choose to. More › Support & feedback lets you send us a bug report, a feature request or a question. When you tap Send, the App sends your message, its type, the App's version and your Android version to our server at api.swapwidget.com, run by Swap Widget LLC. Nothing is sent unless you tap Send, and none of your debts, payments, income or other records go with it. While that page is open, the App also loads your earlier requests and the public updates log from the same server.
A random ID instead of an account. The first time you send a message, the App makes a random code on your phone. It's sent with your messages so you can see your own requests and our replies, and our server keeps only a scrambled (hashed) form of it. It isn't linked to your name, email, Google account or advertising ID. Uninstalling the App or clearing its data makes a new one.
The public updates log. When we reply to a request or start work on it, the request and our reply appear in the App's Updates log, which everyone using Snowball Flow can see, without your name and with only a short piece of the random ID. Please don't put personal details such as names, amounts or account numbers in a message.
Keeping and deleting. Support messages are kept on our server so we can answer them and show the updates log. To have yours deleted, email us and mention roughly what and when you sent.
7 Reminders and Notifications
Payment reminders are worked out on your phone from your own plan and shown as notifications by your phone. They can include a debt's name and the amount due, so depending on your lock-screen settings that text may be visible without unlocking. Recording a payment with a notification's "Mark paid" button requires your phone to be unlocked. You can turn reminders off in the App or in your phone's settings.
8 Permissions
- Notifications: asked for so reminders can be shown. Everything else works without it.
- Internet: used only by Support & feedback, while that page is open and when you send a message. Never at start-up or in the background, and always over an encrypted (https) connection.
- Run at startup, keep awake briefly, network state and foreground service: granted automatically to Android's WorkManager, the system component that schedules the App's reminder checks (for example after your phone restarts). Reminders never use the network.
- Files: the App never asks for access to your files. Imports, exports and backups go through Android's file picker or share sheet, one file you pick at a time.
9 Keeping and Deleting Data
- Your data: kept on your phone until you delete it in the App, use More › Erase all data, clear the App's storage, or uninstall. Erasing also removes the App's safety copies.
- Your files: exported backups and spreadsheets stay wherever you saved them until you delete them.
- Phone backups: copies in your Google account are managed by Google in your account settings.
- Support messages: kept on our server; email us to have yours deleted.
Apart from support messages you chose to send, we hold no data about you, so there's nothing else for us to hand over or delete. If you have a question or request about your privacy, email us and we'll help.
10 Security
Your data is protected by Android's app sandbox on your device. Support messages travel to our server over an encrypted (https) connection. Backup and spreadsheet files contain your financial records, and anyone with a copy can read them, so keep them somewhere you trust.
11 Children's Privacy
Snowball Flow is intended for adults and is not directed at children under 13. We don't knowingly collect personal information from children.
12 Changes to This Policy
If this policy changes, for example when the iPhone version is released, we'll update the date at the top and publish the new version at this address. Significant changes will also be mentioned in the App's release notes.
