Terms of use

Effective 2026-12-01

These terms are between you and Valdemar Kobelis, Sidaronių g. 19, LT-06234 Vilnius, Lithuania, the maker of Period Vault.

Using Period Vault

You may use Period Vault on your own devices for your own use. You must be 13 or older. If you are under 18, ask a parent or guardian before you buy a subscription.

Period Vault is a diary for your cycle. It is not a medical device, not birth control and not medical advice. Predictions are estimates and can be wrong. Read Health information in the app for details.

Your data

Your entries stay on your phone. We do not receive them. You are responsible for keeping your phone and your backup files safe. If you lose your phone and have no backup file, your history cannot be restored. The privacy policy explains this in full.

Period Vault Plus

Basic tracking is free. Period Vault Plus unlocks extra features. You buy it through the App Store or Google Play, and their terms apply to the payment, renewals, cancellations and refunds.

A monthly or yearly plan renews every month or year until you cancel it in your App Store or Google Play settings. Cancel at least 24 hours before the renewal date to avoid the next charge. If the plan includes a free trial, you are charged when the trial ends unless you cancel before then. A lifetime purchase is a one-time payment.

On iPhone, Apple's standard licence terms for apps also apply (apple.com/legal/internet-services/itunes/dev/stdeula).

Changes and availability

We improve Period Vault over time and may change or remove features. If we remove a paid feature you bought, we will offer a fair solution. We will tell you in the app before changes to these terms take effect.

Liability

We build Period Vault with care, but we cannot promise it is free of errors. Nothing in these terms limits your rights under the consumer law of the country where you live.
