Withy — Privacy Policy

Withy keeps your readings on your device. The app never transmits your health data — not to Mossforge, not to anyone else. There is no account to create and nothing to sign in to.

Who this is about

Withy (com.mossforge.withy) is an Android app published by Mossforge, a one-person independent developer. This policy covers the Withy app and this website.

What Withy stores

Everything you enter is written to a database inside the app's private storage on your device:

• The readings you record — blood pressure, weight, blood glucose, body temperature and blood oxygen — and the date and time of each.
• The profile names and descriptions you create, if you log for more than one person.
• Your settings: units, clock format, theme, and which metrics you have chosen to show.

That is the whole list. Withy does not ask for your name, email address, phone number, location, contacts, photos or any device identifier, and it has no way to read them.

What leaves your device

Three things can move the data Withy holds off your device. None of them is Withy sending your readings somewhere, and all three are listed here so the picture is complete.

• Android's own backup. If you have Android Backup switched on for your device, the Android operating system copies Withy's database and settings to your Google account, so a new phone can restore them. This is done by Android, not by Withy, and it goes to your account — not to Mossforge. You can turn it off in your device's system settings, under Google › Backup.
• Files you choose to share. Withy can export your readings as a CSV, a spreadsheet or a PDF. When you share one, Android hands the file to whichever app you pick — email, a messaging app, cloud storage — and what happens to it next is governed by that app, not by Withy. Nothing is exported or shared unless you ask for it.
• Purchases. Withy offers a one-time in-app purchase to unlock unlimited exports and additional profiles. Google Play handles the entire transaction; Withy only asks Google Play whether a purchase exists for your account. Mossforge never sees your payment details, and no reading of yours is involved in a purchase.

Emailing support

Settings has an Email support row that opens your own email app with a message to [email protected]. Withy sends nothing itself — your email app sends the message, and only if you choose to. The draft starts with the app's version and build number, your phone's model and its Android version, so that a report can be acted on, and you can edit or delete any of that before sending. It never includes a reading, a profile name or a setting.

What you send reaches Mossforge, including your email address and anything you write or paste into the message — readings included. Mossforge uses it only to reply to you and to fix Withy.

What Withy does not do

• No accounts, no sign-in, no user profiles held by Mossforge.
• No analytics, no telemetry, no crash reporting, no advertising, no third-party trackers.
• No selling or sharing of personal information — there is none collected to sell.
• No interpretation of your readings. Withy records what you enter and performs plain arithmetic over it — averages, highest and lowest, a trend line. It does not tell you whether a reading is normal, high or concerning, and it is not a medical device. For anything about what your readings mean, talk to a clinician.

Deleting your data

Withy's Settings screen can delete individual readings, everything of a single metric, or every reading it holds. Uninstalling the app removes its database along with it. If Android Backup has already copied your data to your Google account, remove that copy from your Google account's backup settings — Mossforge cannot reach it.

Children

Withy is not directed at children and Mossforge does not knowingly collect anything from anyone. Because the app collects no data at all, it holds nothing about a child any more than it holds anything about an adult.

Changes to this policy

If Withy's handling of your data ever changes, this page changes with it and the effective date above is updated. Material changes will also be noted in the app's release notes on Google Play.
