Phasewell privacy policy
Phasewell is not available yet. This is the pre-release version of this document: it describes the app as it is built today, and it will be finalised before the app is released.
Who we are. Phasewell is made by PT Health & Vital Care, a division of PT TECHNOLOGIES LLC (PT TECHNOLOGIES MCHJ), STIR 313308723, Tashkent, Uzbekistan. Contact: support@techatpt.com.
The short version
- Your cycle, symptom and pregnancy records are stored only on your device, in an encrypted database. We do not receive them.
- You do not need an account, email address or name.
- There is no advertising and no analytics in the app. We never sell your information or use it for advertising.
- Optional features that send anything off your device are off until you turn them on, and are described below.
Information on your device
What you record (period dates, bleeding, mood, energy, sleep, symptoms, cervical secretions, optional sexual activity and contraception, basal temperature, ovulation tests, medication notes, free-text notes, pregnancy dates and notes, bookmarks) and your settings stay on your device. The database is encrypted with a key kept in your device's secure storage. Copies of the app's files in device backups cannot be read without that key, which does not leave the device. You can export your records (CSV, JSON, PDF) and delete them, all at once or one record at a time, in Settings → Privacy Center. If you add the home-screen widget, it shows only neutral words (“Tap to open”) unless you switch discreet widgets off; its text is stored on your device for the widget to read and is never sent anywhere.
Because records stay on your device, uninstalling the app or losing your device deletes them unless you exported them or turned on the encrypted backup.
Information that leaves your device
- Purchases. If you start the trial on iPhone or buy Lifetime Premium, Apple or Google processes the transaction under their own privacy policies. We receive the transaction details needed to confirm your purchase (product, transaction identifier and, on Android, a purchase token). If server verification is enabled, these are sent to our backend, checked with Apple or Google, and we keep a one-way hash of the transaction identifier and the result. They contain no health information.
- Encrypted backup (optional, off by default). If you turn it on, your records are encrypted on your device with a key only you hold (shown to you as a recovery key) and the encrypted file is stored on our backend, hosted on Google Cloud (Firebase) in the United States. We cannot read it. We store it with an identifier derived from your key, not with your name or email. You can delete it at any time; deleting all data in the app also deletes it.
- Free preview check (if enabled). So the 7-day preview cannot be restarted by reinstalling the app, starting it sends, on Android, a one-way hash of an identifier Android gives this app on your device (ANDROID_ID), with the start time; our backend hashes it again with a secret and keeps only that hash and the first start time. On iPhone, the app asks Apple's DeviceCheck service to mark that this device has used the preview; Apple keeps that single flag and we store nothing. Neither contains health information, your name or an advertising identifier, and neither is used for tracking or advertising.
- Partner sharing (optional, off by default; Lifetime Premium). If you invite a partner, your device sends our backend a short summary containing only what you choose (your cycle status, your next estimated period and/or your pregnancy week, plus your display name if you set one), encrypted on your device with a key that travels only inside your invitation. We cannot read the summary. We also store one-way hashes of random identifiers created on your device and your partner's device, which are not linked to your name, email or phone number. Your symptoms, notes, sexual activity, contraception, fertile-window estimates and detailed history are never shared. An invitation can be used once, within 15 minutes. Stopping sharing, sending a new invitation, your partner choosing to stop viewing, or deleting all data deletes the summary from our backend. Your partner sees what you share on their own device; once seen, we cannot control copies they make, such as screenshots. You can share with one person at a time. If your free preview ends without a purchase, your summary stops updating; your partner keeps seeing the last one, with its date, until you stop sharing. If your phone does not update the summary for 90 days (for example, after you uninstall the app), it is deleted from our backend automatically.
- Viewing a partner's summary (optional, free). If you accept someone's invitation, your device keeps the invitation key and a random identifier it creates; our backend stores only a one-way hash of that identifier, so it can check that you were invited. You can view one person's summary at a time; accepting another invitation ends the previous one. Two people can share with each other at the same time; each direction is separate. Tapping Stop viewing, or deleting all data, removes your access and the summary you were viewing from our backend.
- Notifications are scheduled on your device. No notification service receives your information.
- Network metadata. Like any online service, our backend and its hosting provider process your IP address and request details when you use the optional features.
What we never do
Sell or rent personal information; share health information for advertising or marketing; build advertising profiles; include third-party analytics, advertising or tracking SDKs; use AI to analyse your health records.
Children
Phasewell is not available yet. Before it is released, we will set the minimum age for using it and any parental consent rules that apply where it is offered, and publish them here.
Your rights
Depending on where you live, you may have rights to access, correct, delete, restrict or port your data and to withdraw consent. Most of your data is only on your device and fully under your control in the app. For data on our backend (encrypted backup, partner sharing summaries, purchase verification records), contact support@techatpt.com. You may complain to your data-protection authority.
Legal bases and transfers
Before Phasewell is released, this section will set out the legal bases we rely on in each region where it is offered, and how information stored outside your country is protected. Encrypted backups, partner sharing summaries and purchase verification records are stored in the United States.
Changes
We will update this policy before any version of the app that collects or shares information differently, and show the date of the latest version.
