RenalDose

Privacy Policy

Your privacy matters. Here is how we handle your data at RenalDose.

Last updated: April 2026

1. Information We Collect

1.1 Account Information

When you create a RenalDose account, we collect:

  • Name and email address (provided directly or via Google OAuth).
  • Authentication credentials (passwords are hashed and never stored in plain text).
  • Subscription and billing status, including your billing provider and PayPal subscription identifier when applicable.

1.2 Calculation Data

Calculation inputs entered into RenalDose (for example age, serum creatinine, weight, height, race, and medications) are processed in real time to generate dosing recommendations. RenalDose is designed as a session-only calculator. Inputs remain in your browser session and are not stored on our servers.

Do not enter patient identifiers such as names, medical record numbers, phone numbers, or free-text clinical notes. If you export a PDF report, that file is generated for local download and remains under your control.

1.3 Usage Analytics

We collect minimal service telemetry to keep the application secure and reliable, including:

  • Authentication and billing event logs.
  • Browser type and device category.
  • Error and performance logs.

2. How We Use Your Data

We use the information we collect to:

  • Provide, maintain, and improve the RenalDose service.
  • Process subscriptions and manage billing.
  • Authenticate users and secure accounts.
  • Respond to support inquiries and communicate important service updates.
  • Analyze aggregate usage patterns to enhance features and performance.
  • Comply with legal obligations.

We do not sell, rent, or trade your personal information to third parties. We do not use your data for advertising or marketing profiling.

3. Data Storage

RenalDose is hosted on Cloudflare infrastructure. All data is transmitted over HTTPS (TLS 1.2+) and encrypted at rest. Our infrastructure leverages Cloudflare's global network for performance, security, and DDoS protection.

We implement appropriate technical and organizational measures to protect your data against unauthorized access, alteration, disclosure, or destruction.

4. Third-Party Services

We use the following third-party services, each with their own privacy policies. RenalDose is independently operated by Ahmed Fouad from Doha, Qatar.

4.1 Billing

Subscription billing for RenalDose Pro is handled by PayPal. We store only the minimum billing metadata needed to manage access, such as subscription status, gateway name, and subscription identifiers. We do not store full credit card numbers, CVV values, or bank account credentials.

4.2 Authentication

Google OAuth is used as an authentication option. When you sign in with Google, we receive your name, email address, and profile picture. We do not access your Google contacts, calendar, or any other Google services.

5. Cookies

RenalDose uses essential cookies only. We do not use advertising cookies. Our essential cookies are used for:

  • Maintaining your authentication session.
  • Remembering your theme preference (light/dark mode).
  • Storing your cookie consent choice.

You can manage cookies through your browser settings. Disabling essential cookies may affect the functionality of the service.

Under applicable data protection laws, including the GDPR, you have the right to:

  • Access — Request a copy of the personal data we hold about you.
  • Correction — Request correction of inaccurate or incomplete personal data.
  • Deletion — Request deletion of your personal data ("right to be forgotten").

  • Withdrawal of Consent — Withdraw your consent to data processing at any time, where consent is the legal basis for processing.

We retain your account information for as long as your account is active or as needed to provide services. If you delete your account, we will remove your personal data within 30 days, except where we are required to retain it for legal or regulatory purposes.

RenalDose does not retain patient calculation records. Account, subscription, and security logs are retained only as long as necessary for operations, fraud prevention, and legal compliance.

8. Children's Privacy

RenalDose is a professional clinical tool and is not intended for use by individuals under the age of 18. We do not knowingly collect personal information from children. If we become aware that we have collected data from a child under 18, we will take steps to delete it promptly.

9. International Data Transfers

Your data may be processed and stored on servers located in various countries through our use of Cloudflare's global infrastructure. Where data is transferred outside your country of residence, we ensure appropriate safeguards are in place, including Standard Contractual Clauses (SCCs) where required by GDPR.

10. Changes to This Policy

We may update this Privacy Policy from time to time. When we make significant changes, we will update the "Last updated" date at the top of this page and notify you via email or an in-app notification where appropriate.

We encourage you to review this policy periodically. Your continued use of RenalDose after changes are posted constitutes your acceptance of the updated policy.
