What Clinilog knows about you.

Last updated 4 August 2026 Applies to the Clinilog Android app, com.mishtik.health_tracker

Clinilog is a symptom diary. What you put in it is medical information about you, and the whole app is built on the assumption that it should never be seen by anyone you have not personally invited. This page describes exactly what is stored, where it goes, and who can reach it.

What Clinilog stores

Your account

You sign in with Google. Clinilog never sees or handles your password — Google authenticates you and hands the app a user ID. Against that ID the app stores your display name, your email address and the URL of your Google profile picture, so that a profile has a name to show in the switcher when it is shared with someone.

Your check-ins

Each check-in is one record holding the date and which of your daily slots it belongs to, the time that slot was due, the time you actually saved it, and whether it was filled in late. Alongside that are your answers: whether you had a fever and the temperature you entered, whether you had pain and the 1–10 score for each area, which body areas had a rash and whether each itched or hurt, and your fatigue score. A free-text note is stored if you write one — whatever you type there is stored exactly as typed.

A "no" answer is stored as a no, rather than left out, so a question that was asked and answered can be told apart from one that was never asked. Missed check-ins are not stored at all — a missed slot is simply the absence of a record.

Photos

If you attach a photo to a check-in, the image itself is compressed and stored with the check-in it belongs to, along with its size, a category and its creation date. Photos are deleted automatically 60 days after they are taken. Deletion runs within about a day of expiry, and the app filters expired photos when reading, so one is never shown past its date.

Sharing

If you invite someone to view your records, an invitation is stored containing your name and email and the email address you typed. When they accept, that becomes a share record holding both parties' names, emails and user IDs. This is what lets each of you see the share in your own app and revoke it.

Kept only on your phone

Your reminder times are stored on the device, not in the cloud — the phone that shows the notification owns the schedule. They do not follow your account to another phone. Reminders are local alarms; nothing is pushed from a server, and no notification content leaves your device.

What Clinilog does not do

  • No advertising. There are no ads and no advertising SDKs in the app.
  • No analytics or tracking. The app contains no analytics, crash-reporting or attribution SDK. Your behaviour in the app is not measured, profiled or reported anywhere.
  • Nothing is sold or shared for marketing. Your data is never sold, rented, brokered, or handed to anyone for advertising or any other commercial purpose.
  • No public access. There is no link, ID or URL that exposes your records publicly. There is no public read path to any record in the system.
  • No password. Sign-in is Google's, so the app never receives, stores or transmits a password.

Where the data lives

Records are stored in Google Cloud Firestore in the asia-south1 region (Mumbai, India), inside a Firebase project controlled solely by Clinilog's developer. Google acts as the infrastructure provider — it processes and stores the data on Clinilog's behalf under its own security and privacy terms, and Google's operation of that infrastructure involves its own operational logging, which is outside Clinilog's control.

Data in transit is encrypted with TLS, and encrypted at rest by Google Cloud.

Who can see your records

Access is enforced on the server, not in the app, so a modified or malicious client cannot talk its way past it. The rules allow exactly two things:

  • You — the signed-in owner of a record — can read and write it.
  • Someone you have invited and who has accepted can read it, and only for as long as that share exists. They can never edit, add or delete anything, and viewing your records does not put your reminders on their phone.

Removing someone cuts off their access immediately and drops your profile from their app. Sign-in additionally requires a verified email address, so access can never be gained by claiming an address you do not control.

The doctor's report

The PDF report is generated on your phone and shared through Android's normal share sheet. Clinilog does not upload it anywhere and keeps no copy of it. Once you send it — over WhatsApp, email, print or anything else — it is outside Clinilog's control, and the privacy policy of whatever app or service you chose applies to it from that point on.

How long things are kept

  • Photos: deleted automatically 60 days after capture. No action needed from you.
  • Check-ins, profile and shares: kept until they are deleted. Symptom history is only useful over months, so nothing is removed on a timer.

To have your account and everything stored against it deleted, use the account deletion page — it explains exactly what goes and what cannot, and sends the request from the address you signed in with. You can also revoke Clinilog's access to your Google account at any time from your Google account permissions, which stops any further sign-in.

Your choices

  • Revoke any share, at any time, from within the app.
  • Decline or cancel an invitation before it is accepted.
  • Leave the note field, the temperature field and photos empty — every one of them is optional.
  • Request a copy of your data, or delete your account entirely.

Children

Clinilog is not directed at children and is not intended for use by anyone under 13. It does not knowingly collect data from them. If a child's records have been entered, email the address below and they will be removed.

Changes to this policy

If what the app stores or who can reach it changes, this page changes with it and the date at the top is updated. Material changes — anything that widens who can see your records or what is collected — will be called out in the app's release notes, not only here.
