Luna — Free Period Tracker in Telegram

Why Luna?

Most period tracking apps want you to download yet another app, create yet another account, and hand over your most intimate health data to a company that profits from it. Luna takes a completely different approach.

Luna lives inside Telegram — the messaging app you already use. No app store. No registration. No separate password. Just open Luna in Telegram and start tracking. It takes 10 seconds.

We built Luna because we believe cycle tracking should be:

• Effortless: Open Telegram, tap a button, done. No friction, no forgotten apps.
• Private: Your health data shouldn't be a product. Period.
• Accessible: Works on any device that runs Telegram — phones, tablets, desktop.
• Shareable: Partners should be able to understand your cycle without awkward conversations.

Features

How It Works

1. Open Luna in Telegram — tap the button below or search for @lunacycle_bot
2. Enter your last period date — Luna immediately calculates your current phase
3. Log daily (optional) — track mood, symptoms, flow. Takes under 10 seconds.
4. Get predictions — Luna learns your pattern and gets more accurate each cycle
5. Share with partner (optional) — send a partner link for shared cycle awareness

That's it. No account creation. No email verification. No app download. You're tracking within 30 seconds of your first tap.

Partner Mode

Luna's Partner Mode is one of our most loved features. Here's how it works:

• You track your cycle as usual inside Luna
• Generate a private partner link and share it with your partner via Telegram
• Your partner receives their own Luna interface with:
  • Current cycle phase and what it means
  • Daily partner tips ("She might appreciate a quiet evening tonight")
  • Upcoming predictions (period, fertile window)
  • Mood sharing (if you choose to enable it)
• You control exactly what's shared. Revoke access anytime with one tap.

Partners who use Luna report better understanding, fewer misunderstandings, and more proactive support. It turns an invisible biological process into something you navigate together.

Privacy First

Your menstrual cycle data is deeply personal. Unlike most period trackers, Luna was built with privacy as a core principle — not an afterthought.

• No ads. Your data is never used for advertising or sold to third parties.
• No social features. No forums, no "community," no places where data can leak.
• Telegram encryption. Your data is protected by Telegram's infrastructure and encryption.
• Minimal data. We only store what's needed for predictions — period dates, symptoms, and preferences. That's it.
• Delete anytime. One command removes all your data permanently. No retention period, no "we'll keep it for analytics."

"After reading about how Flo was sharing user data with Facebook, I deleted it immediately. Luna in Telegram just feels safer — and it works better for me because I'm already in Telegram all day."

Pricing

Luna follows a generous freemium model:

• 89 days Pro free — full access to all features, no credit card required
• Free forever tier: Basic period tracking, predictions, and reminders remain free forever
• Pro features: Advanced analytics, mood tracking, symptom correlations, partner mode, export, priority support
• Pro pricing: Affordable subscription — less than a coffee per month

We believe everyone deserves cycle tracking. That's why the core experience is completely free forever. Pro features are for those who want deeper insights.

Luna vs. Flo vs. Clue

How does Luna compare to the major period tracking apps?

Luna vs. Flo

• Privacy: Flo has faced multiple controversies about sharing user data with Facebook and Google. Luna doesn't sell or share data — ever.
• Convenience: Flo requires downloading a separate app, creating an account, and granting permissions. Luna works inside Telegram — zero friction.
• Ads: Flo's free version shows ads. Luna is ad-free.
• Partner sharing: Flo doesn't have a native partner sharing feature. Luna's Partner Mode is built-in.

Luna vs. Clue

• Convenience: Clue is a standalone app that requires download, account creation, and regular opening. Luna lives where you already spend time — Telegram.
• Engagement: Many users download Clue but forget to track consistently. Luna's Telegram reminders mean higher engagement.
• Partner mode: Clue doesn't offer partner sharing. Luna does.
• Both excel at: Science-based predictions and educational content.

Why Telegram Wins

The biggest advantage Luna has isn't a feature — it's location. You open Telegram dozens of times a day. You'll never forget to track because Luna is already there, where you naturally spend time. No separate app icon competing for your attention, no login screens, no update notifications. Just seamless tracking woven into your daily messaging.

Frequently Asked Questions

Is Luna really free?

Yes. Basic period tracking, predictions, and reminders are free forever. You get 89 days of Pro features free when you start — no credit card needed. After that, Pro is an optional upgrade.

Do I need to install anything?

No. If you have Telegram on your phone, tablet, or computer, you already have everything you need. Just open @lunacycle_bot and start tracking.

Is my data private?

Absolutely. We don't sell data, don't show ads, and don't share your information with third parties. You can delete all your data at any time with a single command.

How accurate are the predictions?

Luna's algorithm improves with each cycle you track. After 3 cycles, most users see predictions within 1–2 days of accuracy. For irregular cycles, it may take a few more cycles, but Luna adapts to your unique pattern.

Can my partner see everything I track?

You control exactly what's shared. By default, partners see your current phase and basic predictions. You can choose to share or hide mood, symptoms, or any other data. Revoke access anytime.

What if I have irregular cycles?

Luna is designed to handle irregular cycles. The algorithm adapts to your personal pattern, even if it varies month to month. The more you track, the smarter it gets.

Can I export my data?

Yes. Pro users can export their full tracking history. It's your data — you should always be able to take it with you.
