Privacy Policy

When a patient messages a clinic that uses Seshu, the clinic decides why and how the patient’s data is used. Seshu processes that data on the clinic’s behalf, only to provide the service to the clinic.

We store only what is needed to manage appointments:

• Name
• Phone number (WhatsApp)
• Appointment time
• The clinic the patient contacted
• Whether the patient has given consent

We never store complaints, symptoms, diagnoses or other health details. If a message contains this kind of information, its text is not saved and the conversation is handed to the clinic team.

Consent is requested on the patient’s first contact on WhatsApp, before a name or message text is stored. Until then, we keep only the phone number and the consent state, and a patient who does not consent is deleted after 48 hours.

To understand and answer a request, the content of each message is processed. The text of messages is deleted after 3 days by default.

• To answer patients’ administrative questions on the clinic’s behalf
• To book, reschedule and cancel appointments in the clinic’s schedule
• To hand conversations over to the clinic team when needed
• To keep the service secure, prevent misuse and fix problems
• To count conversations per clinic for billing (counts only, not content)

We do not sell personal data, we do not use it for advertising, and we do not use patients’ messages to train AI models.

Seshu uses an AI model to understand messages and to draft replies about administrative matters. Appointment times always come from the clinic’s real schedule and are checked again by the system before a booking is confirmed.

The AI does not make medical decisions. Medical, urgent or unclear messages, and any request to speak to a person, are handed to the clinic team.

We use the following providers to run Seshu. They process data only to provide their service to us, for the purposes above.

Some of this processing happens outside Egypt, for example in the European Union. We limit what each provider receives to what it needs.

Patients can ask to see their data, correct it, or have it erased, and can withdraw consent at any time.

• Through the clinic: contact the clinic you message on WhatsApp. It will handle the request with us.
• By email to Seshu: write to abdelrahmank12a@gmail.com with the WhatsApp number you used and the name of the clinic. We may need to check that the number belongs to you.

When data is erased on request, it is deleted from Seshu. You can still contact the clinic directly, for example by phone.

• Encrypted connections (HTTPS/TLS) between the services that make up Seshu
• Each clinic can see only its own data, enforced by access rules in the database
• Automated services have only the permissions they need
• Access keys are kept in a secrets vault, not in code
• Storing as little data as possible, and deleting it automatically as described above

No system is completely secure. If a security incident affects personal data, we will inform the affected clinics.

This website uses no cookies, analytics, tracking, forms, or third-party scripts or fonts. It is hosted on Cloudflare Pages, which may keep standard technical logs (such as IP address and the page requested) for security.

Seshu is not meant to be used by children on their own. Appointments for a child should be made by a parent or guardian.

Seshu does not handle emergencies. If a message looks like an emergency, Seshu tells the patient to call the ambulance on 123 or go to the nearest emergency department, and alerts the clinic team. In an emergency, call 123 directly — do not wait for a reply on WhatsApp.

We may update this policy. The date at the top shows the current version.

Questions or requests about privacy: abdelrahmank12a@gmail.com.

Patients can also reach us through the clinic they message.
