InBetween Privacy Policy

Effective date: October 30, 2026

Who we are

InBetween is developed by Science of Data (Carolina Bosch).

This policy covers the InBetween beta app for iPhone (through Apple TestFlight) and for Android (through a direct download, and later Google Play testing).

The beta terms are at scienceofdata.inc/beta.

A prototype, not medical advice

Prototype — for development and testing only.

InBetween is not medical advice and does not diagnose or treat any condition.

InBetween is still in development. I'm doing my best to protect your privacy, but as with any early app, security isn't final yet, so share only what you're comfortable with.

What InBetween saves

InBetween saves your setup answers, check-in answers and notes, unfinished check-ins, and a record of changes. It also keeps the dates and settings needed to show your history.

On iPhone, InBetween also saves medication information, reminder settings and any existing dose records.

The app does not ask for your name, date of birth, email, phone number or address.

If you enter your email address on our install page, we use it only to send you the welcome guide.

Where information goes

InBetween keeps its records on your phone. It has no account or cross-device sync, and does not send your answers to our servers or your doctor. If you agree, it sends anonymous usage counts (never your answers) to help us improve. It uses no crash-reporting service of its own.

We do not receive, see, sell or share the information you enter in the app.

Phone backups and copies you choose to share are separate from the records inside the app. See the sections below.

Optional usage counts

When you first open InBetween, it asks whether you want to share anonymous usage counts. Nothing is selected for you, and the app works the same whichever you choose.

If you tick Share anonymous usage counts, the app sends a short message to TelemetryDeck, the service we use to count app use, when you do one of these things:

  • open the app
  • accept the beta terms
  • finish a daily check-in or a weekly check-in
  • save a check-in to finish later
  • view Patterns (the message includes the time range you picked: 14, 30 or 90 days)
  • create a visit summary
  • finish sharing a visit summary (iPhone only; the message does not say where it went)

Each message also carries a random ID made for this copy of the app, the time it happened, the app version and basic phone details such as the phone model, system version and language setting.

The messages never include your answers, scores, symptoms, notes, medications, dates of symptoms, name, contacts or location.

The random ID is not linked to your name, your email or any account, and we do not try to find out who you are from it.

We use the counts to improve InBetween and to report overall numbers about how the beta is used, for example to partners and investors. We do not sell the counts or use them for advertising or tracking.

Like any internet service, TelemetryDeck receives your phone's internet (IP) address when a message arrives. TelemetryDeck says it does not store IP addresses. TelemetryDeck handles the counts for us under its own privacy policy.

On Android, InBetween uses the internet only to send these counts, and only if you agree.

You can turn usage counts on or off at any time in Settings, under Privacy. The change takes effect right away. If you leave it unticked, or turn counts off, the app sends nothing to TelemetryDeck.

Backups on iPhone

In this synthetic beta, InBetween's data and encryption key can be included in encrypted iCloud or Finder backups. A backup may contain an earlier copy of your history. Erasing in InBetween does not erase those backup copies.

Backups on Android

In this synthetic beta, InBetween excludes its app data from Android backups. Do not rely on a phone backup to restore your InBetween history on another phone.

Sharing a PDF (iPhone)

In Visit, you can preview a PDF of your summary before choosing Share. You choose where the PDF goes in the phone's share sheet. Sharing can create a copy outside InBetween. Erasing the app's data does not delete that copy.

Once you share a copy, the app or person you send it to handles it under their own rules.

Apple TestFlight and Google Play

Apple (for TestFlight) and Google (for Google Play) may collect information about testers, such as details needed to invite you and run the test. They handle that information under their own privacy policies, not this one.

How long information is kept

InBetween keeps its records until you erase them.

Usage counts are kept by TelemetryDeck for up to 2 years, then deleted.

Erasing information

In Settings, choose Erase all my data and confirm. This removes the app's records and change history from your phone and removes their encryption key. You cannot undo this in the app.

Erasing does not remove copies in phone backups or copies you have shared outside InBetween. If erasing is interrupted, the app finishes erasing the next time it opens.

Erasing also turns usage counts off, and the app asks you again the next time you set it up. Erasing does not remove counts already sent. Because they are not linked to you, we cannot tell which counts are yours.

If the app's data cannot be opened, the recovery screen offers Start over (erase everything). Confirming this erases the app's data from your phone and starts again with an empty app.

Because we never receive your app data, we cannot erase it for you.

Changes to this policy

We may update this policy as InBetween changes. We will post the new version on this page and change the effective date at the top. If a future version of the app starts sending any information off your phone beyond the optional usage counts described above, we will update this policy before that version is released.
