Privacy Policy
Last updated: 17 February 2026
Introduction
Needled ("we", "our", "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use the Needled mobile application ("the App").
By using the App, you agree to the collection and use of information in accordance with this policy.
Information We Collect
When you create an account and use Needled, we collect the following information:
- Account information: Your name, email address, and securely hashed password.
- Body metrics: Weight entries and progress over time.
- Injection logs: Dates and times of logged injections, and pen dose counts.
- App preferences: Your injection schedule, reminder settings, and display preferences.
- Optional labels: Free-text labels you attach to weight entries (e.g., "Week 3", "5mg").
- Optional custom metrics: You may create and track custom measurements (e.g., body measurements) which are stored with the same privacy protections as weight data.
Information We Do NOT Collect
Needled is deliberately designed to avoid collecting sensitive medical information:
- We do not collect the name of any medication you are taking.
- We do not collect dosage amounts or concentrations.
- We do not collect medical diagnoses, conditions, or treatment plans.
- We do not collect information about your healthcare providers.
- We do not sell, share, or trade your personal data with third parties for marketing purposes.
Third-Party Services
The App uses the following third-party services that may process some of your data:
- Firebase Cloud Messaging: We use Firebase Cloud Messaging to deliver push notification reminders. Firebase stores device tokens and notification metadata. See Google's Firebase privacy policy for details.
- RevenueCat: Subscription purchases are processed through RevenueCat, which maintains customer subscription status. See RevenueCat's privacy policy for details.
How We Use Your Information
We use the information we collect to:
- Provide and maintain the App's core functionality (injection logging, weight tracking, pen management).
- Display your progress data back to you via charts and statistics.
- Send you injection reminders at your requested times.
- Authenticate your account and keep your data secure.
- Improve the App based on aggregated, anonymised usage patterns.
Data Storage and Security
Your data is stored securely using industry-standard encryption both in transit and at rest. We use secure cloud infrastructure to host your account data. Passwords are hashed and never stored in plain text.
While we implement robust security measures, no method of electronic storage is 100% secure. We cannot guarantee absolute security but are committed to protecting your data to the best of our ability.
Data Retention
We retain your data for as long as your account is active. If you delete your account, we will remove your personal data from our active systems within 30 days. Some data may be retained in encrypted backups for up to 90 days before being permanently deleted.
Your Rights
You have the right to:
- Access the personal data we hold about you.
- Correct inaccurate or incomplete data.
- Delete your account and associated data.
- Export your data in a portable format.
- Withdraw consent for optional data processing at any time.
To exercise any of these rights, please contact us at hello@needled.app.
Children's Privacy
Needled is not intended for use by anyone under the age of 16. We do not knowingly collect personal information from children. If we become aware that we have collected data from a child under 16, we will take steps to delete that information promptly.
Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the updated policy within the App and updating the "Last updated" date above.
