Privacy Policy
Contents
This Privacy Policy explains how Nirwan Technologies ("we", "us") collects, uses, shares, and protects your personal data when you use the SehatPlus mobile application ("the app"). We are committed to handling your data responsibly and in accordance with applicable data protection laws.
1. Who we are
SehatPlus is operated by Nirwan Technologies. For any privacy question or request, contact us at contact@nirwantechnologies.com. We act as the data controller for the personal data described in this policy.
2. Scope
This policy applies to the SehatPlus app on Android and iOS. It does not cover third-party services that the app links to or relies on, which are governed by their own privacy policies (see How we share).
3. Information we collect
We collect only what the app needs to work. This includes:
| Category | Examples |
|---|---|
| Account & identity | The email address you sign up with, or the identifier provided when you sign in with Google or Apple, and a unique account ID. |
| Profile | Display name, age, gender, height, weight, activity level, your health goal, food-allergen preferences, and an optional profile photo. |
| Health & nutrition data (sensitive) | The meals and foods you log, portion sizes, calories and nutrients, weight and other health entries, and your history over time. This is treated as sensitive personal data and receives extra protection. |
| Food-scan images | Photos you capture to log or identify food. See Food-scan contribution for how corrected images may be anonymised and used to improve our food-detection model. |
| Health-assistant messages | If you use in-app health-assistant features, the messages you send and the responses you receive, so the conversation works and is available to you. |
| Usage & diagnostics | Anonymous, aggregated analytics about how features are used, and crash and error diagnostics, to keep the app reliable. These events are designed to be free of personal identifiers and free of your health values. |
| Advertising | If you use the free tier, our advertising provider may use a device advertising identifier to serve and measure ads. |
| Purchases | If you subscribe, the app store (Google Play or Apple) processes your payment and provides us a purchase confirmation token to activate your subscription. We do not receive or store your card details. |
We do not collect your precise location. Photos you upload are stripped of location and device metadata before they leave your device (see below).
4. How we use information
- To provide the app: create your account, save your profile, log meals, and track your goals and history.
- To sync your data across your devices and restore it when you sign in.
- To identify foods from photos and barcodes and show nutrition information.
- To keep the app secure, reliable, and free of bugs (diagnostics).
- To understand, in aggregate, which features are used so we can improve them.
- To improve our food-detection model, using only anonymised images you choose to contribute (see below).
- To process subscriptions and provide support.
5. Legal bases
We rely on the following legal bases:
- Consent: for creating your account and processing your health and nutrition data, and for contributing anonymised food images.
- Contractual necessity: to deliver the features you ask for, including subscriptions.
- Legitimate interest: to keep the service secure and reliable and to improve it, where this does not override your rights.
6. Food-scan contribution (optional)
To improve food detection for everyone, we may use food images together with the correction label you provide when you fix an incorrect result. Before any image leaves your device, our privacy pipeline:
- removes all metadata, including GPS location, device information, and timestamps;
- assigns a new random filename that is not linked to your account; and
- compresses the image.
The result cannot be linked back to you. This contribution is optional: you can turn it off in the app's settings at any time without losing access to features. If you opt out, your food images are processed only on your device and are not uploaded for this purpose.
7. How we share information
We do not sell your personal data. We share it only with service providers that help us run the app, under their own privacy terms:
| Type of provider | Purpose |
|---|---|
| Cloud and hosting providers | Account authentication, database and file storage, crash diagnostics, analytics, and app-improvement functions. |
| Advertising providers | Serving and measuring ads on the free tier. |
| Sign-in providers | Letting you sign in with a third-party account. |
| App stores and payment processors | Distributing the app and processing subscription payments. |
| Food-information providers | Looking up packaged-food information by barcode. These lookups do not include your identity. |
We may also disclose data if required by law, or to protect the rights, safety, and security of our users and our service.
8. Where data is processed
Your account, profile, and health data are stored on cloud infrastructure operated by our service providers. Some processing may occur on their global infrastructure, which may be located in other countries. We rely on these providers' security and data-transfer safeguards.
9. Retention
We keep your personal data for as long as your account is active. When you delete your account, we purge your personal data promptly, and any residual copies in backups are removed within 90 days. Anonymised images you contributed are not personal data and may be retained to keep our food-detection model working. Aggregated, non-identifying statistics may be kept indefinitely.
10. Your rights
Subject to applicable law, you have the right to:
- access the personal data we hold about you;
- correct inaccurate or incomplete data;
- delete your data and account;
- obtain and port your data;
- withdraw consent (this does not affect processing already carried out); and
- object to, or restrict, certain processing.
You can edit your profile and delete your account directly in the app (Settings → Delete Account). You can also request any of the above by emailing contact@nirwantechnologies.com. See our account-deletion page for details.
11. Security
Access to your data is restricted to your authenticated account through security rules, transmitted over encrypted connections, and stored with our cloud providers' protections. No system is perfectly secure, but we work to protect your data and to limit what we collect in the first place.
12. Children
SehatPlus is intended for people aged 17 and over. We do not knowingly collect personal data from children under 17. If you believe a child has provided us data, contact us and we will delete it.
13. Changes to this policy
We may update this policy as the app evolves or the law changes. We will update the effective date above and, for significant changes, notify you in the app.
