BIA Male and BIA Female Privacy Policy
Last updated: 2 October 2026
This Privacy Policy explains how X Tech Solutions GT Limited (“X Tech Solutions”, “we”, “us” or “our”) handles information when you use BIA Male or BIA Female on iPhone or Apple Watch (together, the “BIA Apps”).
It covers the features available in your version of the app, including fitness and activity tracking, push-up camera tracking, Body Scan, Food Photo Analysis and, in BIA Female, period tracking.
X Tech Solutions GT Limited is the data controller for personal data processed through the BIA Apps and our BIA Nutrition service.
Company number: 11940011
Registered office: 4th Floor, 18 St. Cross Street, London, England, EC1N 8UN, United Kingdom

Depending on the features you use, the BIA Apps may store or process:
Local information is not uploaded to a BIA user account.
Specified protected files, including Body Scan files, saved food photographs, food entries, cardio caches and BIA Female cycle records, are excluded from iCloud and device backups. Other locally stored information, including push-up preferences, history and calibration data, may be included in device backups according to your Apple settings.
With your permission, the BIA Apps may read relevant Apple Health information, including:
Workout features may write workout and calorie information to Apple Health.
This information is used to display activity, workout and progress information. The Food feature uses active energy to compare logged food calories with active calories burned.
Apple Health information is not included in Food Photo Analysis requests.
The iPhone and Apple Watch apps use Apple’s WatchConnectivity framework to exchange workout state and related information between your paired devices.
Camera permission is used for the camera features you choose, including push-up tracking, Body Scan and taking meal photographs.
These features handle camera information differently:
For Food Photo Analysis, you can also select a specific image using Apple’s photo picker. The app does not upload your entire photo library.
Photographs and camera views may include your face, other people or surroundings. Avoid including unnecessary personal information when using camera features.
Push-up tracking uses your iPhone camera and Apple’s Vision framework to analyse movement on the device.
The feature processes body-position information, including shoulder positions and movement range, to count repetitions and provide tracking feedback.
The app may save:
Live camera frames are processed temporarily. The feature does not save photographs or video recordings of your push-up sessions and does not upload the frames to us, Microsoft Azure or OpenAI.
Calibration information supports movement tracking. It is not used to identify you by name, authenticate your identity or create an advertising profile.
If you choose to share a push-up result, the app creates a result card without a camera image. Information you share through another app or service is then handled under that recipient’s privacy terms.
Body Scan uses your iPhone camera to capture front, side and back views. Apple’s Vision framework processes these views on the iPhone to create silhouettes and body-landmark information for visual comparisons.
The app stores scan dates, derived silhouettes and alignment information. It retains photographs from the first and latest saved scans, with up to three photographs per scan and up to six retained photographs in total.
When a newer scan replaces the latest scan, photographs from the previous latest scan are removed unless they also belong to the first retained scan. Intermediate scan records retain their compact silhouettes and alignment information rather than their photographs.
Body Scan photographs and derived information:
Body Scan uses body outlines and landmarks to align comparisons. It does not use these features to verify your identity.
You can delete an individual scan or use Delete All Body Scans. Deleting a scan removes its saved record and any retained photographs associated with it.
Body Scan provides visual comparisons. It does not measure body composition or provide a medical diagnosis. Clothing, posture, lighting and camera position can affect comparisons.
If you use period tracking, the app stores the cycle settings, period-start dates, flow, mood, symptoms and notes you choose to enter.
This information is used to display cycle history, estimate future dates and provide optional reminders. Previous entries may also be used to identify recurring patterns in logged moods or symptoms.
Cycle information is stored locally with complete file protection and excluded from iCloud and device backups. It is not uploaded to BIA servers or sent to Microsoft Azure or OpenAI.
Cycle predictions are estimates and must not be used as contraception.
When you request meal-photo analysis:
The results may be inaccurate and are not medical or dietary advice. You decide whether to save, edit or discard them.
The BIA Nutrition service does not intentionally save meal photographs in permanent X Tech Solutions storage. Photographs are handled temporarily to process the request.
OpenAI may retain API inputs and outputs in abuse-monitoring logs for up to 30 days by default, or longer where required by law. X Tech Solutions does not opt in to model training using BIA meal photographs.
Food Photo Analysis uses Apple App Attest and a pseudonymous installation identifier to protect the service and enforce its daily analysis allowance.
Information processed for this purpose includes:
These records support security, fraud prevention and fair operation of the service. They are not used for advertising or cross-company tracking.
Microsoft Azure may also process connection and diagnostic information, including IP addresses, request times, endpoints, response statuses, device or network headers and technical error details.
We do not deliberately include meal photographs, Apple Health information or cycle information in application logs. Push-up footage and Body Scan photographs are not sent to this service.
Subscriptions are managed through Apple’s App Store and StoreKit.
Apple handles your Apple ID, payment details and billing information under its own privacy terms. The BIA Apps receive product and transaction information needed to display plans, complete and restore purchases, and determine subscription access.
We do not receive your complete payment-card details.
With your permission, the apps schedule reminders, including hydration, training, workout, Body Scan and, in BIA Female, cycle reminders.
Notification preferences are stored on your device.
Notification content may appear on your lock screen. Detailed period-tracking reminders may include previously logged moods or symptoms when that option is enabled. You can change notification preferences in the app and your device settings.
Apple may provide crash reports and diagnostic information if you choose to share them through your device settings. Reports may contain technical information about your device, app version and errors.
If you contact us, we process the contact details, message and attachments you provide to respond and support you. Please avoid sending unnecessary health information or personal photographs.
Where UK or European data-protection law applies, we process information for the following purposes.
Providing requested features: We rely on the performance of our contract with you, or steps taken at your request before entering a contract, to provide app functions and subscription services.
Health and other sensitive information: Some Apple Health, cycle, fitness, body-image and food information may constitute health information or other special-category personal data. Where required by law, we rely on your explicit consent as the additional condition for processing this information.
Service security: We rely on our legitimate interests in protecting the BIA Nutrition service, preventing abuse, validating installations and operating food-photo allowances fairly.
Support: We rely on performance of our contract and our legitimate interests in responding to enquiries and supporting our products.
Legal obligations: We process information where necessary to meet applicable legal requirements.
Optional diagnostics: Apple’s optional diagnostic sharing depends on your Apple privacy settings. We use reports received to investigate faults and improve reliability, based on our legitimate interests in maintaining the apps.
You can withdraw consent for future processing by stopping the relevant feature, changing permissions or contacting us. Withdrawing consent does not affect processing that was lawful before withdrawal. Turning off a permission does not automatically delete information already saved.
Apple provides the App Store, StoreKit, HealthKit, App Attest, WatchConnectivity, notification services, photo picker and optional diagnostics.
The apps also use Apple’s Vision framework locally. Using Vision for push-up tracking or Body Scan does not mean those camera images are uploaded to Apple.
Apple’s handling of information through its services is described in the Apple Privacy Policy.
Microsoft Azure hosts the BIA Nutrition service and its security and food-photo allowance records.
Microsoft’s handling is described in the Microsoft Privacy Statement and applicable service terms.
OpenAI provides the API used to analyse optional meal photographs.
Its handling is described in the OpenAI Privacy Policy and API data controls.
Push-up camera frames and Body Scan photographs are not sent to OpenAI.
If you share a result or send information through another app, the recipients and services you select receive that information.
We may disclose information we hold to professional advisers, regulators, law-enforcement bodies or courts where required by law or reasonably necessary to establish, exercise or defend legal claims.
We do not sell Apple Health information or disclose it to advertising platforms, data brokers or the BIA Nutrition service.
The production BIA Nutrition service is hosted on Microsoft Azure in the United States. OpenAI may process Food Photo Analysis information in the United States or other countries where it or its providers operate.
Optional meal photographs, analysis results and associated security or request information may therefore be processed outside the United Kingdom or European Economic Area.
Where required, we use recognised transfer safeguards, such as applicable adequacy decisions or regulations, approved standard contractual clauses and the UK International Data Transfer Addendum. You can contact us for information about the safeguards relevant to your data.
Push-up camera processing and Body Scan processing occur locally on your iPhone and do not involve these service transfers.
Camera frames are processed temporarily and are not saved as session photographs or videos.
Push-up session history and baseline-change records are retained for today and the previous 29 calendar days. Expired records are removed when the app next performs its cleanup.
Your current baseline, target, progression and saved calibration are retained beyond that history period so the feature can continue across sessions. They remain until replaced or the app’s local data is deleted.
Photographs are limited to the first and latest retained scans, with up to six photographs in total.
Photographs from intermediate scans are removed as newer scans are saved. Silhouettes, alignment information and scan dates remain for comparisons until you delete the relevant scans or the app’s local data.
Deleting an individual scan removes its associated retained photographs and record. Delete All Body Scans removes all saved Body Scan records and retained photographs.
Saved food entries and resized photographs remain on your iPhone for today and the previous 29 calendar days before automatic deletion. You can delete entries sooner.
Meal photographs sent to BIA Nutrition are handled temporarily to process the request and are not intentionally placed in permanent X Tech Solutions storage.
OpenAI may retain API inputs and outputs in abuse-monitoring logs for up to 30 days by default, or longer where required by law.
Hydration history is retained locally for up to 180 days.
Detailed BIA Female cycle logs are retained locally for up to 90 days. Current cycle settings and up to seven recorded period-start dates may remain until replaced or the app’s data is deleted.
Other histories, goals and preferences remain for the relevant feature’s history period or until you reset the feature, delete the information or remove the app.
Support correspondence and required business records remain for as long as reasonably necessary to resolve requests and meet legal, accounting or dispute-resolution requirements.
Deleting an app normally deletes its local data from that device. Information already written to Apple Health must be managed separately. Apple-held purchases, diagnostics and backups are subject to Apple’s policies and your settings.
You can:
Some features require permissions or information to work. Revoking access stops future use of that permission but does not automatically remove previously saved records.
Depending on where you live and the circumstances, you may have the right to:
To exercise your rights, contact support@xtech.solutions.
Because the apps do not require a BIA account, we may need additional information to locate and verify relevant server records.
We cannot remotely access or retrieve information that remains only on your device, including locally stored Body Scan records and push-up history. We can explain the available controls for that information.
UK users can complain to the Information Commissioner’s Office. You may also contact the relevant regulator where you live.
We use safeguards appropriate to the information and feature, including:
These protections do not mean every app preference or history record is excluded from backup.
No system can be guaranteed completely secure. Protect your device with a passcode and keep iOS, watchOS and the BIA Apps updated.
The BIA Apps are not directed to children under 13.
Where a person is below the age at which they can provide valid consent for the relevant processing in their country, parental or guardian authorisation is required where applicable.
Parents and guardians should consider camera access, body photographs and health information when supervising use.
If you believe we have processed a child’s personal data without appropriate authorisation, contact support@xtech.solutions.
We may update this policy when app features, service providers or legal requirements change.
We will publish the revised version on our Privacy Policy page and update the date shown above.
Where a change materially affects how an optional feature handles sensitive information, we will provide an appropriate notice in the app.
