Privacy Policy
App: MeSize Last updated: July 16, 2026
MeSize ("MeSize", "we", "us", or "our") built the MeSize mobile app (the "App") to help you save and organize your own clothing and shoe sizes, body measurements, and a personal catalog of the items you own. This Privacy Policy explains what information the App handles, how it is used, and the choices you have.
We designed MeSize to be private by default: everything you enter stays on your device unless you choose to create an account and turn on cloud backup.
MeSize is operated by an independent individual developer based in Poland, not a registered company. Where this document says "we", it refers to that operator (the data controller), who you can reach at the contact address in Section 13.
1. Summary
- The App works offline-first. Your sizes, measurements, catalog, and photos are stored locally on your device by default.
- Creating an account (Sign in with Apple or Google) is optional and only needed to back up and sync your data across devices.
- Cloud backup and sync are part of the optional one-time Premium purchase.
- We use no third-party advertising, analytics, or tracking SDKs. We do not sell your personal data and we do not use it for advertising.
- You can delete your account and all cloud data at any time from within the App.
2. Information We Handle
2.1 Information you provide
- Size & body profile: profile name, gender, build type, home country, preferred unit system (cm/in), body measurements you enter (such as chest, waist, foot, head, and finger), and the clothing/shoe sizes you save (US/EU/UK/JP).
- Catalog items: the items you add, including brand, category, size, notes, and any photos you attach.
- Custom categories you create.
- App preferences: theme, language, and onboarding status.
2.2 Account information (only if you sign in)
- When you use Sign in with Apple or Sign in with Google, we receive a secure identity token and basic profile information — typically your email address and, where available, your name. If you use Apple's *Hide My Email*, we only ever receive Apple's private relay address.
- We use this to create and authenticate your account and to attach your backup and your Premium entitlement to you.
2.3 Purchase information (only if you buy Premium)
- Premium is a one-time in-app purchase processed by the Apple App Store or Google Play. Your payment is handled entirely by Apple or Google — we never receive your card or payment details.
- To unlock Premium for your account, we verify your purchase with Apple's App Store Server API or Google's Play Developer API using the transaction identifier or purchase token supplied by the store, and we store a record of whether your account is entitled to Premium.
2.4 Information we do not collect
- We do not collect your precise location.
- We do not use advertising identifiers or third-party trackers.
- We do not access your contacts, and we do not scan your photo library beyond the specific photos you choose to attach to catalog items.
3. Device Permissions
- Photo library: requested only when you attach a photo to a catalog item, so you can pick an image.
- Camera: requested only if you use camera-based measuring features.
You can change these permissions at any time in your device settings. Denying them only disables the related feature.
4. How We Use Information
We use the information above to:
- provide the core features of the App (save, display, and organize your sizes, measurements, and catalog);
- authenticate your account and keep your data in sync across your devices (when you sign in with Premium);
- verify and honor your Premium purchase;
- remember your preferences (theme, language);
- respond to your support requests; and
- maintain the security and integrity of the service and comply with law.
We do not use your information for advertising or profiling, and we do not sell it.
5. Where Your Data Is Stored
- On your device: by default, all of your data is stored locally using the device's app storage.
- In the cloud (optional): if you sign in and have Premium, your profiles, catalog items, custom categories, app settings, and catalog photos are backed up to our backend, which is hosted on Supabase (a third-party cloud infrastructure provider). Photos are stored in a private storage bucket and served to you through short-lived signed links. Data in transit is protected with encryption (HTTPS/TLS), and data at rest is protected by the hosting provider.
If you never sign in, no personal data leaves your device through the App.
6. Sharing and Sub-Processors
We do not sell or rent your personal information. We share information only with service providers that help us operate the App, and only as needed to provide it:
| Provider | Purpose | Data involved |
|---|
| Apple | Sign in with Apple; App Store purchase & receipt validation | Identity token, email/name, purchase transaction |
| Google | Sign in with Google; Google Play purchase validation | Identity token, email/name, purchase token |
| Supabase | Cloud database, authentication, file storage, and backend functions | Account, profile, catalog, photos, entitlement |
Each provider processes data under its own privacy terms. We may also disclose information if required by law, to enforce our Terms, or to protect the rights, safety, and security of our users or the public.
7. Data Retention
- Local data remains on your device until you delete it or uninstall the App.
- Cloud data is retained for as long as your account exists so that your backup stays available. When you delete your account (see below), your cloud data and stored photos are permanently removed.
8. Your Rights and Choices
Depending on where you live, you may have rights to access, correct, export, or delete your personal data, and to object to or restrict certain processing.
- Access & correction: your data is visible and editable directly in the App.
- Deletion: you can permanently delete your account and all associated cloud data and photos at any time from Settings → Account → Delete account. This cannot be undone. You can also remove local data by deleting items in the App or uninstalling it.
- Withdraw from cloud: simply sign out to stop syncing; your data remains on your device.
- Requests: to exercise any right, contact us at the address in Section 13. We will respond within the time required by applicable law.
- Complaint: if you are in the EEA or UK, you may lodge a complaint with your local data-protection authority. In Poland this is the President of the Personal Data Protection Office (UODO).
9. Security
We use reasonable technical and organizational measures to protect your information, including encryption in transit, private storage with signed access links, and access controls that ensure each account can only read its own data. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
10. Children's Privacy
MeSize is not directed to children under 13 (or the minimum age required in your country, such as 16 in parts of the EEA). We do not knowingly collect personal information from children under that age. If you believe a child has provided us personal information, contact us and we will delete it.
11. International Users
Your information may be processed and stored in countries other than your own, including where our hosting provider operates. Where required, we rely on appropriate safeguards for such transfers. By using the App, you understand your information may be transferred as described in this policy.
12. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above and, for material changes, provide a more prominent notice within the App. Your continued use of the App after an update means you accept the revised policy.
