A lightweight cycle tracker that lives in a Telegram chat: log your period dates, see when the next one is likely and get a reminder before it starts.
VitaFlow Cycle Assistant describes itself as a private cycle tracker that is lightweight, secure and right inside Telegram, and the lightweight part is the easiest to see. There is no mini app and no separate download: you tell the bot when your period starts, it keeps the dates, predicts when the next one is due and sends a reminder shortly before it arrives.
That narrow scope is the point. If the full-featured period apps feel like more than you need, a bot that only remembers dates and nudges you ahead of time covers the everyday question of when to expect the next period. It is also handy for travel and busy weeks, since the reminder comes to the same place as your messages.
The word private deserves a closer look. The bot publishes no website, developer name or privacy policy, so there is nothing to confirm how the dates are stored or whether you can delete them. Pricing is not published either, and its Telegram page shows no monthly-user count, which means a small audience. Despite the shared name, it has nothing to do with the VitaFlow supplement and fitness brands. Forecasts are estimates from your own history and become less reliable with an irregular cycle.

No. It is an independent Telegram bot that happens to share the name.
The bot says so, but it publishes no privacy policy or developer, so that cannot be checked. Log only what you are comfortable sharing.
