How does the size recommendation work?
Sizemira builds a “body twin” on your phone from the measurements you enter. When you add a product, it finds the brand’s official size chart for that category and department and compares each size’s measurement range with yours.
- The fabric’s stretch (elastane content), the product’s cut and your fit preference (tight, regular, relaxed) are taken into account.
- Each size gets a match score. The size with the highest score is recommended. If two sizes are very close, the app says you are “between two sizes”.
- Confidence depends on where your measurements come from (a tape measure or a size you know), the chart’s source and whether the fabric is known.
- From the “How did it fit?” answers of users who allow sharing, the app learns whether a brand tends to run small or large and adds this to the recommendation. This needs answers from at least 8 different devices in a group.
- If the brand has no chart, a standard chart is used and confidence is lower.
A recommendation is an estimate. For the best results, take your measurements with a tape measure and keep them up to date in “Edit twin”.
The link could not be read or the page did not open
The product page is opened and read on your phone. Sometimes the product details can’t be read:
- “The page did not open”: the page did not answer in time or the connection dropped. Check your internet connection and try again.
- “… keeps its pages closed to apps”: the shop does not show its pages to apps.
- “We could not read the product from the page”: the page opened, but no product details were found.
In all three cases you can carry on: on the “Check the product” screen you pick the brand, category, department and cut in a few taps, and if the fabric could not be read, you are asked how stretchy it is. Make sure the link starts with https:// and is a product page. Without a connection, you can continue by picking the brand. If a particular shop keeps failing, send us the link.
The barcode was not recognised
If you see “We don’t know this product yet”, paste the product’s link or pick its brand. The barcode is then linked to that product. If sharing is on, it is recognised at once next time for other users too. If camera permission is off, you can turn it on in your phone’s Settings or type the number on the label.
How do I delete my data?
Profile → Privacy and data → Delete my data. This deletes your body twin, analyses, closet and settings on your phone, and your device record, product contributions and feedback on our server. It can’t be undone.
- Without a connection, the data on your phone is deleted at once and the server deletion happens automatically once you are online.
- Deleting does not cancel your subscription. Your Plus status and the free plan’s monthly counter stay on the phone.
- If you uninstalled the app without using “Delete my data”, we can’t link the data on our server to you. If you send us the device ID from a file you exported earlier, we will delete it.
If you only want to stop sharing, turning off the sharing switch in Profile is enough. Details: Privacy Policy.
How do I export my data?
Profile → Privacy and data → Export my data. The app creates a JSON file with all your Sizemira data on the phone and your device ID, and opens the share sheet. You can save the file to Files or send it to yourself. The app has no import.
How do I cancel my subscription?
Subscriptions are managed through Apple or Google. To stop it renewing, cancel at least 24 hours before the period ends.
- iPhone: Settings → your name → Subscriptions → Sizemira Plus → Cancel Subscription.
- Android: Google Play → profile icon → Payments & subscriptions → Subscriptions → Sizemira Plus → Cancel subscription.
- While Plus is on, Profile → Manage subscription in the app takes you straight there.
When you cancel, Plus stays on until the end of the period you paid for. Deleting the app does not cancel the subscription. For refunds, use reportaproblem.apple.com on the App Store and Google Play’s refund page on Google Play. Details: Terms of Use.
How do I restore my purchases?
If you moved to a new phone or reinstalled the app, make sure you are signed in with the Apple or Google account you bought the subscription with. Then tap Restore purchases in Profile or on the Plus screen. If you see “No active Sizemira Plus subscription was found on this account”, a different store account may be signed in on the phone. Plus does not move between Apple and Google.
What does the free plan include?
8 new product analyses every 30 days, a 20-item closet, and results with the recommended size, the overall verdict and the first 2 reasons. Opening or re-running a saved analysis does not use an analysis. Plus makes analyses and the closet unlimited and unlocks the zone map, the confidence percentage and the two-size comparison.
The “How did it fit?” notification
When you tap “I bought this size” for an item, you get one notification 14 days later. It is scheduled on your phone, not sent from our server. You can turn it off in Profile → Settings. Even if you don’t allow notifications, unanswered items are asked about on Home.
