YOSS Support
Help with the current YOSS web app, Telegram Mini App and bot: sign-in, Pro, your records and notifications.
YOSS helps you reflect on daily energy, water balance and readiness through YOSS Score and related insights. Scores, patterns and forecasts are model estimates based on available records and assumptions. They are not medical measurements, diagnoses or guarantees of how you will feel.
Getting started and signing in
Complete the introduction, open Today and add your records. The local core works without an account. Guest records stay in this browser’s local storage. Export the records you need before clearing it or changing devices.
Account services use verified Telegram sign-in; there is no email and password registration. In a browser, start sign-in from Account and follow the confirmation instructions. For bot confirmation, compare the code, approve only your own request and return to the same browser tab. Opening the Mini App does not sign in a separate browser tab.
If the request expires, start a new sign-in request. Use the same Telegram account when recovering purchases or moving devices. Do not send support Telegram login codes, passwords or bot tokens.
Pro trial
An eligible signed-in Telegram account can explicitly start one 14-day Pro trial after three different activity dates have been recorded by the server. Opening YOSS does not start it. Use the trial button when the offer becomes available.
The trial has no automatic charge. Monthly renewal is a separate purchase choice. Deleting data, reinstalling or linking accounts does not reset trial eligibility. Check Account for your access status and dates.
Buying Pro with Telegram Stars
When sales are enabled, open Account and the Pro access options. The current monthly offer is 249 Stars for a recurring 30-day period. One-time prepaid options cover 1–9 months or one year and do not renew automatically. Before paying, check the price, duration, start date and renewal terms shown in the offer.
A one-time period can follow your existing access. Turn off monthly renewal before buying the next period as a one-time payment; your paid time remains available. A visible catalogue does not by itself mean checkout is enabled. If purchases are unavailable, return later or contact support.
Access is granted after the payment provider’s confirmation has been verified. An invoice, screenshot or closed payment window does not itself confirm successful payment. If the outcome is unclear, check access and restore or contact payment support before trying another payment.
Restoring a purchase
Sign in to the same Telegram account used for the purchase. Open Account and choose Restore purchase. Then check the access status and dates. Restore checks entitlement and does not make a new purchase.
If the payment is confirmed but access is missing, use Payment support or /paysupport in the bot. Include the date, plan and payment reference if available. Do not send your full health record or payment credentials.
Cancelling monthly renewal
In Account, open your access details and choose Cancel renewal when renewal is on. Check that the status changes to automatic renewal off. Turn renewal off before the next charge; paid access continues until its displayed end date.
Prepaid periods and the trial have no automatic renewal. Deleting local data, deleting the bot conversation or stopping use is separate from cancelling a recurring purchase.
Payment questions and refunds
Use Payment support, /paysupport in the bot or the email below. Describe what happened and include the payment reference if available. A request does not mean a refund has been approved. Applicable consumer rights and the payment provider’s rules continue to apply.
If your purchase was made through the App Store in a separately distributed native Apple version, Apple handles that purchase, its subscription management and applicable refund process. The Telegram Stars instructions on this page apply to web and Telegram purchases.
Records, cloud copies and changing devices
Local records and account records have different storage paths. Sync and cloud copies are initiated by your selected actions. Records entered through the bot are saved on the server directly. Enabling background delivery can first sync the account.
Before clearing browser storage or changing devices, export the data you need. On the new device, sign in to the same Telegram account for account services and use the available sync or import controls. Review records, corrections and conflict choices before accepting them. Signing in alone does not confirm that every local record has moved.
Apple Health files
The web and Telegram app can work with an Apple Health XML export through its import control. Choose export.xml; compatible evidence is imported on your device. Check the imported evidence afterwards. File import does not give the browser direct HealthKit access. Apple Watch is not required to use YOSS or enter records manually.
Deleting data
Local reset, deletion of cloud data and deletion of a Telegram conversation are separate actions. Use the relevant data controls in YOSS and read the confirmation. Before cloud deletion, an active monthly renewal must be successfully disabled. Minimal purchase, trial and entitlement records can remain as explained in the Privacy Policy.
Notifications and reminders
Use the notification settings to choose the available channels and schedule, and to pause or disable delivery. Browser push requires permission and support from your browser and operating system. Telegram delivery requires an available bot chat.
Delivery depends on the device, network and third-party services; arrival at an exact time is not guaranteed. A dispatch already authorised before you turn a channel off may still arrive. If a reminder is missing, check permissions, the chosen time zone and schedule, pauses and whether the bot is blocked.
YOSS is for lifestyle awareness. Do not rely on notifications or score estimates for emergencies or medical decisions.
Language and appearance
The current app supports Russian, English, Spanish, Japanese, Kazakh, Brazilian Portuguese, Turkish and Uzbek. Choose your language and the available appearance option in Settings.
