Iron LiftVault — Privacy Policy
Iron LiftVault is a gym workout log: you record the exercises, sets, reps and weights you lifted, and it keeps them. This policy explains what happens to that information. The short version is that it stays on your phone.
Summary
- There is no account and no sign-in. The app never asks who you are.
- Iron LiftVault has no server. Your workouts are never uploaded, because there is nowhere to upload them to.
- The app requests no runtime permissions — no camera, no microphone, no location, no contacts, no storage.
- It works fully offline. Logging a workout in airplane mode behaves identically.
- There is no analytics and no crash reporting.
- Some versions carry an optional rewarded video advert, described below. It only ever plays if you tap a button asking for one, and never during a workout.
What is stored, and where
Everything below lives in the app's own private storage on your device:
- Workouts — the exercises, sets, reps, weights, set types and times you logged.
- Routines you build, and their target sets and reps.
- Body weight entries, if you choose to record them.
- Preferences — kilograms or pounds, rest timer length, accent colour.
None of it is transmitted to Nivaro Studios, and we have no way to see it. Uninstalling the app, or clearing its data in Android Settings, erases all of it.
Taking your data with you
Settings contains an export that writes every workout and weight entry to a CSV or JSON file and hands it to Android's share sheet, so you can send it wherever you like. It is free, it is not behind an advert, and it does not require anything of you. The data is yours.
Advertising
Iron LiftVault is distributed in two forms. Some channels receive a build with no advertising code at all. Others receive a build containing a single optional advert, served by Google AdMob.
Where it is present, the advert is:
- Rewarded video only. There are no banners and no full-screen interruptions.
- Shown only when you ask for one, by tapping a clearly labelled button in Settings that offers to unlock extra accent colours.
- Never shown during a workout — not between sets, not when you finish, not on the summary.
- Purely cosmetic in what it unlocks. No part of logging, history, routines, progress or export is behind it.
When you choose to watch one, Google AdMob may collect your device's advertising identifier, approximate location derived from your IP address, and information about the device, in order to select and measure the advert. That processing is governed by Google's privacy and terms for partner sites. We receive only aggregate counts of how many adverts were shown; we never receive anything that identifies you.
In the European Economic Area and the United Kingdom you will be asked for consent before any personalised advert is served, using Google's own consent interface. Declining is a supported answer and the rest of the app behaves identically.
A build carrying advertising declares the advertising identifier permission
(com.google.android.gms.permission.AD_ID). A build without advertising declares no
permissions at all.
Analytics and crash reporting
There are none, in either build. We do not know how many workouts you log, how often you open the app, or whether it has ever crashed for you. If something goes wrong, the only way we learn of it is if you write to us.
Health information
What you record here — weights lifted, body weight — may be sensitive to you even where it is not legally classed as health data. It is treated accordingly: it stays on your device, we never receive it, and it is never sent to an advertising network or any other third party.
Iron LiftVault is a logbook, not a coach or a medical device. The estimated one-rep max it displays is calculated from repetitions you completed using a standard formula; it is an estimate drawn from population averages, not a weight you have lifted and not a target to attempt. Nothing in the app is medical advice. If exercise causes you pain, dizziness or any other concerning symptom, stop and speak to a qualified professional.
Children
Iron LiftVault is not directed at children under 13 and is not listed in a children's category. Because the app collects nothing from anyone, nothing is held about a user of any age.
Your rights and deletions
Everything lives on your own device, so you are in direct control:
- Export everything from Settings at any time.
- Delete individual workouts, routines and weight entries inside the app.
- “Delete all data” in Settings erases everything the app holds.
- Uninstalling the app, or clearing its data in Android Settings, does the same.
We hold no copy, so there is nothing for us to delete on your behalf and no request to make. If you have a question, write to support@nivarostudios.com.
Exercise content
The exercise list and the demonstration photographs come from the open Free Exercise DB, released into the public domain under the Unlicense. The written instructions are our own.
Grievance redressal
India's Digital Personal Data Protection Act 2023 requires a published point of contact for privacy questions and complaints. For every Nivaro Studios app that is:
Grievance Officer, Nivaro Studios
support@nivarostudios.com
Delhi, India
We acknowledge a grievance within 48 hours and aim to resolve it within 30 days.
Withdrawing consent
There is no consent to withdraw for the app itself, because it collects nothing. Advertising consent, where it was requested, can be changed from the same Google consent interface, and declining leaves every other part of the app working exactly as before.
If there were ever a breach
Your training stays on your phone, so there is no server of ours holding it and no database of ours to breach. In the unlikely event of an incident that nonetheless affected you, we would publish it on this page and notify affected users within 72 hours of becoming aware of it.
Changes to this policy
If this policy changes, the effective date above changes with it. Any change affecting what the app collects will be published here before the version that introduces it, not after.
