Privacy Policy
Applies to: BrandSize · Last updated: October 8, 2026
This page is the privacy policy for the Android app "BrandSize" (Japanese name ふくのサイズ, package name app.minimalab.brandsize, "the App"). A separate general privacy policy for minimalab is also available, but for matters specific to the App, the contents of this page take precedence.
1. Information We Collect
minimalab, the developer of the App, does not collect any information that directly identifies you, such as your name, email address, phone number or location. The sizes, measurements, photos and notes you record in the App are never sent to minimalab.
To show ads in the free version, the following information may be handled by the advertising SDK:
- Google Advertising ID
- Device information (general details such as OS version, device model, language and screen size)
- Anonymous statistics about ad impressions and interactions
This information is processed directly by the advertising SDK (Google AdMob) and is not sent to or stored on minimalab's servers. See "3. Third-Party Services" for details.
In regions where consent is required, such as the EU/EEA, the UK and Switzerland, the App shows a consent screen through Google UMP (User Messaging Platform) at launch. Personalized or non-personalized ads are served according to your choice. You can change your choice at any time from "Ad privacy choices" in the App's Settings.
2. Data Stored on Your Device
The following data is stored on your device and is never sent to minimalab's servers (for how Android's standard backup handles it, see "5. Android Auto Backup").
| People | Names you give, body measurements (optional: height, chest, waist, hips, inseam, foot length, foot girth, head circumference), a profile photo (optional) |
|---|---|
| Brands | Brand names you type, a picture you set for a brand (optional) |
| Records | Category, label size, fit ratings, garment measurements, photos (size tag and whole item, optional), item name, notes, product page URL, date |
| Next sizes | The size and note you pinned for a brand |
| App settings | Measurement unit, theme, whether to add the app name to shared text, the last person you selected, the number of tips received through "Support the developer" |
| Device-only settings | Screen scale for the on-screen ring gauge; records used to ask for an in-app review (the number of days you opened the App and whether we have asked); the date until which update prompts are paused after you choose "Later" |
| Pro purchase status | A local cache of the purchase status from Google Play Billing |
Photos are ones you pick with Android's photo picker or take with your camera app. The App makes a resized copy in its own storage. The App does not read any other photos on your device.
Uninstalling the App deletes all of this data from your device.
Data that leaves the device when you choose to send it
Only in the following cases does some or all of your data leave the device, and only through your own action. You choose the destination; minimalab never receives it.
- Sharing sizes: the records you choose (person, category, brands) are sent as text or an image through Android's share sheet
- Export: your records and photos are saved as a ZIP file to a location you choose (on the device or a cloud drive)
URLs received through sharing
When you open the App from the share menu of a shopping app or browser, the App only stores the URL and product name you shared in the new record. The App never opens or fetches that URL (no page content or images are retrieved).
3. Third-Party Services
The App uses the following third-party services. For how these services handle data, please see Google's Privacy Policy.
- Google Play Billing — Used to process the one-time Pro purchase and "Support the developer" tips (optional payments that unlock nothing), and to check your purchase status. Payments and receipts are handled by Google Play.
- Google Play In-App Review and In-App Updates — Used to show the screen for rating the App, and to check for and download new versions. Both work through the Google Play Store app on your device and do not send your records, photos or other user data. The App is not told whether you wrote a review or what it says.
- Google AdMob — Used to show a banner ad at the bottom of the screen in the free version. Users who purchased Pro are not shown ads, and no ad requests are made for them. However, when consent allows, the advertising SDK is initialized at launch regardless of purchase status, so it may communicate with Google's servers as needed for its own operation.
- Google UMP (User Messaging Platform) — Used to show the ad consent screen required by regional laws such as the GDPR. Whether consent is required is checked at launch regardless of purchase status.
The App does not include Google Analytics for Firebase, Crashlytics or any other analytics or crash-reporting SDK.
4. App Permissions
The App uses the following Android permissions, each only to the extent needed for its features.
| Internet | To serve ads and process purchasesINTERNET |
|---|---|
| Billing | To process the Pro purchase and "Support the developer" tips (added by the Google Play Billing library)com.android.vending.BILLING |
In addition, the advertising SDK (Google Mobile Ads) adds permissions for its own operation: network state (ACCESS_NETWORK_STATE), advertising ID (AD_ID, ACCESS_ADSERVICES_*), keeping the device awake (WAKE_LOCK) and foreground services (FOREGROUND_SERVICE). The App itself does not use them.
The App does not request camera, storage (photo and video access), location or contacts permissions. Photos come only through Android's photo picker and your camera app, one photo at a time, as you choose.
5. Android Auto Backup
Android's built-in backup (cloud backup to your Google account and device-to-device transfer) is enabled.
- Cloud backup: your record data and app settings may be stored in your Google account's backup space, according to your device settings. Photos are not included (exceeding the size limit would stop the whole backup from updating)
- Device-to-device transfer (moving to a new phone by cable or wirelessly): record data, settings and photos are transferred
The backup space is managed by Google; minimalab cannot see its contents.
The Pro purchase status cache is excluded from both, to prevent Pro from being enabled improperly through a restore. To enable Pro on a new device, tap "Restore purchase" in Settings to fetch your purchase status from Google Play again. There is no extra charge if you use the same Google account. The device-only settings (the ring gauge's screen scale and the review and update prompt records) are also excluded, as they have no meaning on another device. The number of tips received through "Support the developer" is backed up with the app settings, so it comes back after a reinstall or on a new device.
To move everything including photos, use "Export (ZIP)" and "Import" in Settings.
6. Children's Privacy
The App is intended for people aged 18 and over. Parents may record their children's clothing sizes and body measurements; as described in "2. Data Stored on Your Device", this data stays on the device and is never received by minimalab. We do not knowingly collect personal information from children under 13.
7. Changes to This Policy
This policy may be updated without notice as features are added or laws change. When we make significant changes, we will update the "Last updated" date on this page.
