Privacy Policy
remain.fit is a suite of small, single-purpose health tools built on observation over judgment. That principle applies to your data too: we collect the minimum needed to run the tools you use, we don't sell it, and we don't build advertising profiles from it. This policy explains what we collect, why, how it's protected, and the rights you have over it.
01Who we are
remain.fit (the "Service", "we", "us", "our") is operated by BYTSOLV DIGITAL TRANSFORMATIONS PRIVATE LIMITED, a company incorporated in India (CIN: U62099KL2023PTC083187), with its registered office at 37/1993, Infra Futura Building, 8th Floor, Kakkanad, Thrikkakara, Ernakulam, Kerala, India, 682021. We are the data fiduciary responsible for personal data processed through the Service.
For any privacy question, you can reach us at legal@remain.fit. Details of our Grievance Officer are in section 14.
02Scope of this policy
This policy covers the remain.fit website, web application, and mobile applications, together with the tools offered within them (such as fasting tracking). It does not cover third-party services you reach through links from the Service, which have their own privacy policies.
This policy is published under India's Digital Personal Data Protection Act, 2023 (DPDP Act) and the Information Technology Act, 2000 and rules made under it, including the Reasonable Security Practices Rules, 2011. Where you access the Service from outside India, your data is still processed as described here.
03Information we collect
We collect only what a tool needs to function. We do not require your real name, phone number, or address to use the Service.
| Category | What it includes | How we get it |
|---|---|---|
| Account & identity | Email address, display name, and a unique account ID; profile photo URL where your sign-in provider supplies one. | From you, via Google Sign-In or Sign in with Apple when you create an account. |
| Health & activity data | Fasting sessions (start/end times, targets, durations), body measurements such as weight and blood pressure, settings, and aggregated stats you generate by using the tools. | Created by you as you use the Service. |
| Medical test results | Results you choose to record from lab reports: the measurement, its value and unit, the reference range printed on your report, the date, and the lab's name if you enter one. We do not store the report document itself. | Entered or pasted by you, or read from a report you upload. Pasted text is read on your own device; an uploaded PDF or photo is sent to Google's Gemini service to be read back as text. We use a paid service tier, on which Google does not use your content to train its models, and we do not keep the file afterwards. You check every result before it is saved. |
| Preferences | Time zone, theme choice, which tools you have enabled, and onboarding state. | Set by you or detected from your device (e.g. time zone). |
| Technical data | Device and browser type, and security signals used to verify that requests come from a genuine app instance (via Firebase App Check). | Automatically, when you use the Service. |
| Usage data | Which pages, screens and tools you open on the website and in the apps, how far you get through the app’s introduction, when you sign in or create an account, whether you are using a guest session, and approximate location (city level, derived from your IP address by our analytics provider). This is about how the Service is used, never about what you record in it. | Automatically, when you use the Service. |
| Payment data | Subscription status and transaction identifiers for any paid features. We do not receive or store full card numbers. | From our payment processor when you purchase a paid feature. |
Sensitive personal data. Your fasting, body-measurement and lab-result data relates to your health and is treated as sensitive. We process it only to provide the tools you actively use, and never for advertising or profiling. It is readable only by your own account, and deleting your account removes all of it. remain.fit is a record-keeping tool: it does not diagnose, interpret or advise, and reference ranges shown alongside a result are either the ones printed on your own report or general adult ranges shown for context.
04How we use your information
We use your information to:
- authenticate you and keep your account secure;
- provide, operate, and sync the tools you use across your devices;
- calculate and display your own metrics (durations, targets, streaks, and other summaries);
- remember your preferences, such as theme and time zone;
- process and manage subscriptions for paid features;
- understand which parts of the Service are used, so we know what to improve;
- maintain security, prevent abuse, and diagnose technical problems;
- comply with legal obligations and respond to lawful requests.
We do not sell your personal data, and we do not use your health data to serve advertising or to build marketing profiles.
05Consent & lawful basis
We process your personal data on the basis of your consent, given when you create an account and use the tools, and to perform the service you have asked us to provide. Where you provide sensitive (health-related) data, you consent to us processing it for the specific purpose of operating the tool you are using.
You may withdraw your consent at any time by deleting the relevant data or your account (see Your rights). Withdrawing consent does not affect processing already carried out, and may mean parts of the Service can no longer function.
07Data storage & transfers
Your data is stored and processed on infrastructure operated by our service providers, which may be located outside India (for example, in Google Cloud data centres in other regions). Where personal data is transferred across borders, we rely on the safeguards and contractual protections offered by those providers, consistent with applicable law.
08Security
We apply reasonable security practices to protect your data, including:
- encryption in transit (HTTPS/TLS) and encryption at rest on our providers' infrastructure;
- strict access rules so that each account can read and write only its own data;
- app-integrity verification to reduce automated abuse.
No method of transmission or storage is completely secure. While we work to protect your data, we cannot guarantee absolute security. If we become aware of a personal-data breach affecting you, we will notify you and the relevant authority as required by law.
09Data retention
We keep your personal data for as long as your account is active, or as needed to provide the Service. When you delete specific entries, they are removed from your account. When you delete your account, we delete or irreversibly anonymise your personal data within a reasonable period, except where we must retain certain records (for example, transaction records) to meet legal, accounting, or security obligations.
10Your rights
Subject to applicable law, you have the right to:
- Access: obtain a summary of the personal data we hold about you and how it is processed;
- Correction: correct inaccurate or incomplete data (much of which you can edit directly in the app);
- Erasure: delete your data or your account;
- Withdraw consent: stop processing based on consent, going forward;
- Grievance redressal: raise a complaint with our Grievance Officer;
- Nominate: nominate another person to exercise your rights in the event of death or incapacity, as provided under the DPDP Act.
To exercise any of these rights, email legal@remain.fit. We may need to verify your identity before acting on a request. If you are not satisfied with our response, you may complain to the Data Protection Board of India.
11Children & minimum age
The Service is intended for users aged 16 and over. We do not knowingly collect personal data from anyone under 16. If you believe a child under 16 has provided us with personal data, contact us and we will delete it. Because the Service involves health-related tracking such as fasting, it is not designed for children.
13Changes to this policy
We may update this policy as the Service evolves or the law changes. When we do, we will revise the "Last updated" date above, and for material changes we will provide a more prominent notice. Continuing to use the Service after an update means you accept the revised policy.
14Grievance officer & contact
In line with India's Information Technology Act and the DPDP Act, you can contact our Grievance Officer with any complaint about how your data is handled. We will acknowledge your complaint within the timelines required by law.
