Privacy Policy
Stub is a bookkeeping app that runs entirely on your iPhone. There is no account, no upload and no bank connection. We only receive personal data when you choose to email us.
Operator: Texture Factory (Hangzhou) Technology Co., Ltd. · Effective: October 9, 2026
Data we collect
Nothing, unless you email us (see Feedback below). We run no servers for this app, and it contains no advertising, analytics or tracking code. Everything you enter in your ledger stays on your device, and we cannot see or access it.
Data stored on your device
Entries, accounts, categories, notes, tags, budgets, recurring plans, templates, refunds and reimbursements, loans, credit-card statements, edit history and app preferences are stored in the app's on-device storage and used only to show your ledger.
Permissions
Face ID, Touch ID or the device passcode is used only if you turn on App Lock; iOS performs the check and the app only learns whether it succeeded. Notifications are requested only if you turn on local reminders. The app does not use the camera, photos, microphone, location, contacts, calendars or health data.
Subscriptions
Pro subscriptions are sold and charged by Apple under the Apple Privacy Policy. The app checks your subscription status on-device through StoreKit; we never receive your name, Apple Account or payment details.
Export and backups
JSON and CSV exports are not encrypted; you decide where they go. Device backups (iCloud or computer) may include the app's data and are handled by Apple or your computer. Diagnostics are created only when you export them or attach them to a problem report, and contain no amounts, names, notes or device identifiers.
Feedback and offer codes
Settings › About › Feedback (设置 › 关于 › 意见反馈) opens your mail app with our address, a subject and a few prefilled lines: a feedback ID (a random string such as S-7K2M-QX9D generated on your device, not derived from any device identifier, Apple Account or ledger data, and replaced if you reinstall the app), the app version and build, iOS version and model code (for example iPhone16,1). Problem reports also attach the no-ledger diagnostics. You can see and edit all of it before sending; nothing leaves your device unless you tap Send.
When you email us we receive your email address, your message and anything you attach. We use it only to reply, fix problems, improve the app, and to send you a Pro offer code as thanks when we adopt your suggestion or confirm a problem you reported. We never use it for advertising, sell it or share it, except where required by law. Mail is stored with our email provider (Google Workspace), whose servers may be outside mainland China, and kept for up to 2 years after the issue is closed; you can ask us to delete it sooner at any time.
Offer codes are Apple subscription offer codes, redeemed in the app (Stub 会员 › 兑换码) or in the App Store. Apple handles redemption and the subscription; we do not receive your Apple Account details.
Retention and deletion
Data stays on your device until you delete entries, use "Clear all ledger data" in Settings, or delete the app. Files you exported and system backups are not affected. Because we never hold your ledger data, we cannot restore it for you. To access, correct or delete emails you sent us, contact us.
Children
The app is not directed to children under 14.
Changes and contact
We will post any update on this page. If we ever add features that process personal data, we will explain them and ask for consent before they are enabled. Contact: developer@txturefty.com.
