MinSoo Go (the “Developer”) complies with applicable privacy laws, including the Personal Information Protection Act of Korea, and publishes this Privacy Policy for “Wimmy” (the “Service”).
1. Information We Collect
Wimmy has no sign-up and never asks for your name, email, or phone number.
- All data you enter — transactions, accounts, budgets, savings goals, categories — is stored on your device and in your own iCloud account, and is not stored on the Developer’s servers.
- iCloud storage is used only to sync your data across your devices. It lives in your personal iCloud space provided by Apple, and the Developer cannot access it.
- The only exception: when you explicitly run an AI auto-entry feature (receipt/payment-screen scan, payment-text paste, or natural-language quick entry), the image or text is transmitted for analysis as described in Section 4.
2. App Permissions
The Service optionally uses the following permissions:
| Permission | Purpose | Required |
|---|---|---|
| Notifications | Budget alerts and upcoming recurring-payment reminders | Optional |
| Camera | Photographing receipts (AI scan feature) | Optional |
| Photo Library | Importing receipt/payment screenshots (AI scan feature) | Optional |
| Face ID | App lock | Optional |
You can change permissions anytime in iOS Settings. Features unrelated to a denied permission continue to work normally.
3. Network Communication
The Service communicates with external services only for the purposes below.
| Destination | Purpose | Data Transmitted |
|---|---|---|
| Korea Public Data Portal (data.go.kr) | Fetching Korean public holiday information | None |
| Apple iCloud | Syncing data to your own iCloud account | Your entered data (stored only in your iCloud) |
| RevenueCat | Verifying and restoring subscription status | Anonymous identifier, App Store purchase receipt |
| Amplitude | Anonymous usage statistics for product improvement | Anonymous device identifier, screen/feature events (never the amounts or contents you enter; no personal identification, no ads or tracking) |
| Developer’s relay server (Cloudflare) and Anthropic | AI auto-entry (Section 4) | The image you select or the text you enter |
4. AI Auto-Entry Features
The following happens only when you explicitly run recognition in the receipt/payment-screen scan, payment-text paste, or natural-language quick entry features:
- What is transmitted: the receipt/payment-screen image you took or selected, or the text you entered; an anonymous device identifier; an anonymous subscription identifier; and (for quick entry) the names of the categories you created and the reference date, used to improve recognition accuracy.
- How it is processed: the data passes through the Developer’s relay server (Cloudflare Workers) and is analyzed by the AI processor (Anthropic, Claude API).
- Storage: transmitted images, text, and analysis results are never stored on any server (they are processed transiently and discarded). Recognition results are stored only on your device. The server keeps only a usage count keyed to an anonymous device identifier to manage free-tier and premium daily limits; the premium daily count is automatically deleted after 48 hours. Server operation logs contain no images or transaction contents. Anthropic does not use transmitted data to train AI models and deletes it after a limited retention period for operational and safety purposes.
- Please note: payment texts and app-notification screenshots may contain third-party information such as sender names. Recognized content is stored only on your device and is never shared.
- If you never use these features, no image or text is ever transmitted.
International Transfer
During AI analysis, data is temporarily transferred to overseas processors:
| Recipient | Country | Purpose | Data | Retention |
|---|---|---|---|---|
| Cloudflare, Inc. | USA | Relaying analysis requests, managing usage counts | Image/text (transient), usage count keyed to an anonymous identifier | Images, text, and results not stored; premium daily usage count auto-deleted after 48 hours |
| Anthropic, PBC | USA | AI image/text analysis | Receipt/payment-screen image or text | Deleted after a limited retention period; not used for training |
5. Third Parties and Processors
The Developer never sells or shares your personal information. The following processors are used to operate the Service:
| Processor | Task |
|---|---|
| RevenueCat, Inc. | Subscription status management |
| Anthropic, PBC / Cloudflare, Inc. | AI image/text analysis (only when you run it) |
| Amplitude, Inc. | Anonymous usage statistics |
6. Data Retention and Deletion
- Your data is stored on your device and in your own iCloud. Deleting the app removes on-device data; iCloud-synced data can be deleted in iOS Settings (Settings → Apple Account → iCloud → Manage App Data).
- You can export your records to a CSV file in the app at any time.
7. Your Rights
You can view, edit, and delete your data directly in the app at any time.
