Routine diary use keeps readings on your device. There’s no account and no automatic sync between Chrome and Telegram.
Some Telegram report and export actions use server processing when you request them.

The adult guide
Start with the reading. Not the app.
Feeling well is not the whole picture.
You can feel well and still have high blood pressure. It usually has no symptoms; a blood pressure check is how you find out. [1] [2]
Untreated high blood pressure can damage the heart and kidneys and contribute to stroke. Checks help make an otherwise unseen problem visible. [1]
The first number (systolic, or SYS) is pressure when the heart beats. The second (diastolic, or DIA) is pressure when the heart rests between beats. Blood pressure is expressed in millimetres of mercury (mmHg). [1] [2]
Illustrative numbers only, not a target or a health assessment. Interpretation depends on the setting and the person; ask a healthcare professional about your readings.
A calm setup. A supported arm. A written record.
The steps below follow the NHS-hosted NIHR / British Hypertension Society guide. General adult guidance; children, pregnancy and individual medical needs require tailored advice.
Use an upper-arm blood pressure monitor and follow its instructions for fitting the cuff. Use the arm your doctor or nurse asks you to use. Avoid tight clothing around that arm. [2] [3]
For 30 minutes beforehand, avoid smoking, caffeine and exercise. Use the toilet if you need to. Then sit quietly and rest for at least five minutes. [3]
Sit with your back supported, feet flat on the floor and legs uncrossed. Rest your arm on a firm surface, palm upwards, with the cuff at heart level. [3]
Stay relaxed and do not talk during the reading. Take at least two readings, at least one minute apart. Write down the exact numbers for each reading rather than rounding them. [3]
Do not wait for the diary if you are unwell or have worrying symptoms. Seek medical help; see WHO’s symptoms and urgent-care guidance, and use your local emergency service when needed. [1]
Keep your readings to share with your healthcare professional. Home measurements do not replace a professional assessment. [1] [2] [3]
Paper is a perfectly good place to start. If you prefer a digital diary, Blood Pressure Tracker keeps readings, pulse, dates and notes together and helps you prepare a report.
The diary does not measure blood pressure. It records the numbers from your own monitor. It does not diagnose a condition or recommend treatment.
Privacy / the boundaries
Local-first does not mean that nothing ever leaves your device. Here is what stays local and what happens when you choose to share.
The website has no diary, health-data form, account, analytics tracker or third-party runtime scripts. Viewing the guide does not transfer readings from either diary. Product links open the Chrome Web Store or Telegram without attaching your readings or Telegram identity.
Like other websites, hosting receives technical connection information, including your IP address and browser details. Hosting and reverse-proxy technical logs may record requests. We do not promise that these logs do not exist. Following an external link puts you under that service’s policies.
Readings and settings are stored in this extension’s local browser storage (chrome.storage.local). Ordinary diary use does not upload them to a backend. Reports are generated locally; exporting or printing creates files that you control.
Readings and settings are stored in the Telegram WebView on your device, using IndexedDB with a localStorage fallback. They are not automatically synchronized with Chrome or another device.
Choosing Create and send doctor report sends selected readings, optional patient details and signed Telegram launch data to the backend. The backend uses the launch data to identify the recipient, generates the PDF and sends it to your private bot chat. This is an explicit action, not ordinary local diary use.
The report-delivery path does not persist report contents on the backend or create a public PDF URL. Telegram stores the delivered PDF until you delete it. Telegram has its own retention and privacy rules; deleting local readings does not delete that chat document.
In Telegram, Download CSV sends the selected readings to the backend to create a temporary file link. The temporary download is separate from PDF delivery and is not a permanent backup. Outside the Telegram WebView, CSV generation can be local. A downloaded file remains wherever you save it.
If you send feedback in Settings, the message you type and Telegram launch data go to the backend so feedback can be delivered with limited user/technical context. Readings, notes, reports and backups are not attached automatically. Avoid putting private health information in feedback.
The published Telegram Mini App uses Umami Cloud to count successful opens. Technical connection data, including IP address and browser details, can reach Umami. The sanitized open event does not include readings, notes, reports, backups, Telegram IDs or the launch URL. The educational website does not use this tracker.
Mini App hosting also receives connection information. Technical logs and client error/download events can contain narrow operational metadata; local-first is not a guarantee of zero technical logging.
Chrome and Telegram maintain separate diaries. JSON import is explicit. The current Telegram WebView says JSON backup is not available in Telegram yet when export is attempted; do not assume that button has saved a backup. Chrome JSON export works locally. See Help for current limitations.
Clearing browser or Telegram app data, reinstalling an app, uninstalling the extension or changing devices can remove local readings. Make and verify backups where available. JSON transfers readings only, not saved patient details. CSV and PDF are reports, not a restore backup.
Exported files contain health information. Store them carefully, share only with intended recipients and consider whether your chosen file-storage location synchronizes to a cloud service. Deleting the diary does not delete exported files or Telegram documents.
Reviewed against current client code on 10 October 2026. No compliance certification is claimed.
Help / the practical bits
Take the measurement with your own monitor, then record it in the diary you choose.
No. You need a blood pressure monitor. The app is a diary for readings you enter yourself.
No. They keep separate local diaries. Chrome can export a JSON backup for manual import; Telegram currently supports import but not JSON export inside its WebView. See Help for the limitations and the distinction between a backup and a report.
Clearing browser or Telegram app data, uninstalling or changing devices can remove your diary. Keep a JSON backup somewhere safe. Exported files contain health information.
Official references are linked beside the relevant claims. Our sources and editorial policy explain scope and review dates. The organizations cited do not endorse this app.
Download CSV creates spreadsheet rows for the selected report period. It is not a full restore backup. In Telegram it uses a temporary backend download link; accepting a download handoff does not prove the file is saved. Check the saved file, or use the visible Open file now fallback when offered.
In Chrome’s Report → Backup & restore, choose Export JSON backup to save your readings. Keep the file somewhere safe and verify it exists. Choose Import JSON backup in the other diary and select the file; review the import result. JSON transfers readings only, not saved patient details. There is no automatic sync.
Local storage can be cleared by app/browser settings, uninstalling or changing devices. Import a previously saved JSON backup if you have one. This website cannot recover local readings or inspect your diary.
Telegram’s Settings includes a feedback form. No readings are attached automatically; avoid including private health information in your message. For medical questions, contact a healthcare professional rather than product support.
