FREQUENTLY ASKED QUESTIONS

My heart rate isn't showing up.

- If you're using a Bluetooth chest strap: make sure it's powered on and worn snugly, then open the heart rate sheet (tap the heart icon on the home screen) and tap "Scan again."

- If you're using an Apple Watch: make sure it's unlocked, paired, and that Health access is turned on for this app under Settings → Privacy & Security → Health. Without the watch companion app installed, readings sync from Apple Health every few minutes rather than live — install the companion app on your watch for a continuously live reading.

Can I build my own interval workout?

Yes. Tap "Custom" on the home screen, then set your own warm-up, work interval, recovery interval, rounds, and cool-down. Saved custom workouts appear alongside the built-in protocols.

Does my workout history sync anywhere?

Workout history is stored locally on your device. If you've enabled Apple Health access, completed workouts are also written to Apple Health, so they'll appear there and on any other device connected to the same Apple Health account via iCloud.

How do I change the language or appearance?

Tap the globe icon on the home screen to change the app's language, or the contrast icon to switch between light, dark, and system appearance.

I found a bug or have a feature request.

Email us at the address above with as much detail as you can — what you were doing, what you expected, and what happened instead. Screenshots help a lot.

Do you sell or share my data?

No. See our Privacy Policy for full details on what data the app uses and why.

Privacy Policy for VO2 Max Intervals

Last updated: September 12, 2026

Ashen Ishanka ("we," "us," or "our") developed VO2 Max Intervals (the "App"). This policy explains what data the App uses, how it's used, and who it's shared with.

SUMMARY

VO2 Max Intervals does not require an account, does not run its own servers, and does not collect or store your personal data on any server we operate. Your workout data stays on your device (and, if you choose to enable it, in Apple Health). The only outside party involved is Google, for the ads that support the free version of the App.

INFORMATION STORED ON YOUR DEVICE

The App stores the following locally on your device, and never transmits it to us:

- Interval protocols you build or customize

- Your workout history (protocol used, duration, rounds completed, date)

- Optional profile details you choose to enter (age, sex) — used only to calculate heart rate zones and training estimates on-device

- Your language and appearance (light/dark) preferences

- The ID and name of a Bluetooth heart rate device you've connected, so the App can reconnect automatically next time

This data can be erased at any time by deleting the App.

HEALTH DATA

If you grant permission, the App reads and writes data to Apple Health (or Health Connect on Android), specifically:

- Heart rate readings, to show your live heart rate during a workout

- Completed workout sessions, so they appear in your Health history

This data is governed by Apple's (or Google's) Health platform and your own device permissions, which you can review or revoke at any time in Settings → Privacy & Security → Health. We never receive a copy of this data ourselves — it moves directly between the App and the Health platform on your device.

BLUETOOTH

The App uses Bluetooth only to scan for and connect to heart rate monitors you choose to pair with it. This requires Bluetooth permission on your device. We do not use Bluetooth for advertising, tracking, or location purposes, and no Bluetooth data leaves your device.

APPLE WATCH

If you use the optional Apple Watch companion app, heart rate data is sent directly from your Watch to your iPhone using Apple's WatchConnectivity framework. It does not pass through us or any third party.

ADVERTISING

The free version of the App shows ads served by Google AdMob. AdMob may collect technical information such as your device's advertising identifier, general device information, and approximate (coarse) location derived from your IP address, in order to serve and measure ads. The App does not request App Tracking Transparency permission, so it does not access your device's IDFA for tracking you across other companies' apps or websites. Ad measurement instead relies on Apple's privacy-preserving SKAdNetwork.

For more detail on how Google handles this information, see Google's Privacy Policy: https://policies.google.com/privacy

CHILDREN'S PRIVACY

The App is not directed at children under 13, and we do not knowingly collect personal information from children.

DATA RETENTION AND DELETION

Locally stored data (history, custom protocols, preferences) is deleted automatically when you uninstall the App. Health data is retained according to your Apple Health / Health Connect settings, independent of the App. You can revoke Bluetooth or Health permissions at any time from your device Settings.

CHANGES TO THIS POLICY

We may update this policy from time to time. Changes will be posted here with an updated "Last updated" date.

Getting Started

How To

How To

1. Introduction

This Privacy Policy describes how Aivora Lab ("we", "us", or "our") handles information in connection with the BirthdayApp mobile application ("App") available on the Apple App Store and Google Play Store.

By using BirthdayApp, you agree to the practices described in this policy. If you do not agree, please discontinue use of the App.

2. Information We Collect

We do not collect any personal information. BirthdayApp does not require you to create an account, sign in, or provide any information to us.

📱 All data you enter — names, birth dates, notes, and preferences — is stored exclusively on your device using your device's local storage. This data is never transmitted to any server or shared with any third party.

The App does not collect or access:

Your name, email address, or contact information
Your device's contacts or address book
Your location
Camera, microphone, or media library
Any analytics or usage data
Crash reports or diagnostics sent to our servers

3. Local Data Storage

BirthdayApp stores birthday records you create directly on your device using standard platform storage (iOS: UserDefaults / Android: SharedPreferences). This data is:

Only accessible by the App on your device
Not backed up to our servers (though it may be included in your device's own iCloud or Google Drive backups, subject to your device settings)
Permanently deleted when you uninstall the App

4. Local Notifications

BirthdayApp uses local notifications to remind you of upcoming birthdays. These notifications are:

Scheduled entirely on your device — no data leaves your device to generate them
Not connected to any push notification service or external server
Controlled by you via your device's notification settings

You can revoke notification permissions at any time in your device's Settings → Notifications → BirthdayApp.

5. Third-Party Services

BirthdayApp does not integrate any third-party analytics, advertising, crash-reporting, or tracking SDKs. We do not use:

Google Analytics / Firebase Analytics
Facebook SDK / Meta Pixel
Crashlytics, Sentry, or similar crash-reporting tools
Any advertising networks

6. Children's Privacy

BirthdayApp is rated 4+ and is suitable for all ages. The App does not knowingly collect personal information from anyone, including children under the age of 13. Since no data is collected at all, the App is compliant with COPPA (Children's Online Privacy Protection Act) and similar regulations.

7. Data Security

Because your data never leaves your device, the primary security of your birthday data depends on your device's own security measures (passcode, Face ID, Touch ID, etc.). We encourage you to use a secure device lock.

8. Your Rights

Since we do not collect any personal data, there is no data held by us to access, correct, export, or delete. All data you enter in the App can be deleted by you at any time within the App, or by uninstalling the App.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected with a new "Last updated" date at the top of this page. We encourage you to review this policy periodically. Continued use of the App after changes constitutes acceptance of the revised policy.

10. Governing Law

This Privacy Policy is governed by the applicable laws of the jurisdiction in which Aivora Lab operates. By using the App, you consent to the terms set forth in this policy.
