Privacy notice

Cparzha is a WhatsApp assistant that helps your doctors follow your blood pressure or your diabetes between visits. This page explains which information it uses, who sees it and what you can do about it.

Who is responsible

Cparzha (preview, sample data) is responsible for your data. Contact: contact@example.org.

Why your data is used

• to remind you to take your medicines;
• to receive the readings you send and show them to your doctors;
• to warn your doctors when a reading is outside the usual range;
• to answer simple questions about your follow-up;
• to pass on to your doctors the questions the assistant cannot handle, and send you their answer.

Your data is not used for advertising and is never sold. It is used because you agreed to it when you activated the service.

Which data

• your name, date or year of birth, sex, language, the condition being followed and the WhatsApp number used (yours or a relative’s);
• your town, to give you the right emergency number;
• the medicines your doctors prescribed, with doses and times;
• the advice each doctor leaves you (diet, activity): the assistant reminds you of it, but never gives doses;
• your readings: blood pressure, pulse, blood sugar;
• whether you report having taken each dose;
• the messages, photos of your device and voice notes you send to the assistant;
• the documents you send: lab results, imaging, prescriptions, discharge reports, payment receipts;
• your conditions, allergies, medical history, surgeries, vaccinations, family history and other current medicines, noted by your doctors, including what you report to the assistant;
• what your doctor notes at your first consultation: the reason for the visit, blood pressure, blood sugar, weight and height, tobacco and alcohol, pregnancy, and the date of your next check-up.

Who receives it

• Your doctors: several doctors can follow you. Each one sees your readings, medicines, alerts and messages, and manages the medicines and measurement plans they prescribed. A doctor can only reach your file if you give them the 4-digit code the assistant sends you. They then choose either to follow you, until they stop or you remove them, or to read your file for 24 hours for a single visit. Your phone number and the access history are visible only to the doctors who follow you. Your doctors may also write each other notes about your treatment. Every view, change, answer, note and removal is recorded in the access history. Your doctors also see your medical documents, but never your payment receipts, which are kept for you only. Your conditions, allergies and medical history form one shared record that every doctor who follows you can complete; each change is kept with its author and date. What you report to the assistant enters that record only after a doctor checks it. At your request, a doctor can make a condition confidential: only that doctor sees it, with its medicines and documents, and its reminders do not name the medicine. In an emergency, another doctor can see it for 24 hours by giving a reason, or with your code; that emergency access is recorded and the condition’s doctor is told.
• Meta (WhatsApp) carries the messages between you and the assistant.
• Artificial-intelligence providers, reached through the company OpenRouter, receive the content of your messages so that the assistant can understand them. Your name is removed first and your phone number is never sent. These providers are not allowed to use your data to train their systems. A document sent as a file (a PDF, for example) is never sent to them, nor are your conditions, allergies and medical history, your first consultation or the name of a confidential medicine.
• The hosting company stores the data on servers located in Germany.

Meta and the artificial-intelligence providers process data outside Burkina Faso, in particular in the United States and in Europe. The data travels encrypted, and each provider is bound by a contract that limits what it may do with it.

Artificial intelligence

The assistant uses artificial intelligence to read the values in your photos, voice notes and texts, and to sort your messages. The colour given to a reading comes from fixed medical thresholds, not from the artificial intelligence. Decisions about your care are made by your doctors. You can ask how a result was obtained and contest it through your health centre.

How long it is kept

• Your file: for as long as at least one doctor follows you with Cparzha.
• After the follow-up ends: 2 years, then it is deleted.
• After you ask for deletion: 30 days, during which you can change your mind, then it is deleted.
• Photos and voice notes: 90 days, except a photo kept as a document.
• Your documents: for as long as your file exists; they are deleted with it.
• The record of who consulted your file: 2 years.
• A file that was created but never activated: 30 days.
• Backup copies: 14 days. Deleted data disappears from the backups within 14 days.

Your rights

You can see your data, have it corrected, object to its use, withdraw your agreement and have your data deleted.

• Reply STOP to the assistant: the reminders stop at once.
• Reply DELETE: your data is deleted after 30 days. Reply CANCEL before then to keep it.
• Write MY DOCTORS, or use the menu, to see your doctors and remove one at any time. Their medicines keep their reminders; your other doctors can stop them.
• Choose My documents in the menu to get any of your last 10 documents again. For a copy of all your documents, ask your health centre.
• Choose My health record in the menu to get your full record as a PDF: conditions, history, treatment, first consultation, readings of the last 90 days and the doctors following you. A PIN code is asked for before it is sent.
• Choose Who saw my record in the menu to see the last 10 times a doctor opened your record, and whether it was emergency access.
• Choose PIN code in the menu to protect your health record, your documents, your doctors’ answers and the list of who saw your record with a 4-digit code. On a shared phone, each person can have their own. If you forget it, a doctor who follows you can remove it.
• To see or correct your data, or for any question, contact your health centre: contact@example.org.

Stopping Cparzha does not change the care you receive from your doctors. You can also lodge a complaint with the data protection authority of Burkina Faso, the Commission de l’Informatique et des Libertés (CIL).
