Privacy policy

Effective 2026-12-01

Period Vault is a period tracker. It is made by Valdemar Kobelis, Sidaronių g. 19, LT-06234 Vilnius, Lithuania. You can reach us at support@periodvault.com.

This policy is written for the version of Period Vault that has no account and no analytics.

The short version

• Your cycle data stays on your phone.
• We have no server for your cycle data. We cannot see it. We cannot give it to anyone.
• There is no account and no sign-up.
• There are no ads, no trackers and no analytics in the app.
• We do not sell or share your data.
• Purchases go through Apple or Google.
• You can delete everything in the app at any time.

What the app stores on your phone

When you use Period Vault you can enter period dates, symptoms, notes and settings. The app stores them in a database on your phone. This is information about your health. It is only on your device.

We do not receive it. We do not have access to it. We do not process it on any server.

The app uses your entries to show your calendar and to estimate your next period. If you turn it on, it also shows an estimated ovulation day. It does this on your phone. The estimate uses the average length of your recent cycles. It is a rough guide, not medical advice.

What the app does not do

• It does not ask for your name, email, phone number, date of birth or location.
• It does not read your contacts, photos, calendar or health apps.
• It does not use Apple Health or Health Connect.
• It does not use advertising IDs.
• It does not send your cycle data to us or to anyone else.

Phone backups

Phones can back up app data to the cloud. Apple has iCloud Backup. Google has Android backup to Google Drive.

We switched this off for the Period Vault database. Your cycle data is not in your iCloud Backup. It is not in your Google backup. It is not in a backup you make to a computer.

This protects your privacy. It also means that if you lose your phone or get a new one, your history does not come back by itself. To keep it, make an export file (see below) and import it on the new phone.

Export file

In Settings you can export your data to a file. The app asks you to choose a passphrase and encrypts the file with it. You choose where to save or share the file. We never receive it.

We cannot open the file. We cannot recover your passphrase. If you forget it, the file cannot be read.

Once you save the file somewhere, such as a cloud drive or an email, that place has its own rules and its own privacy policy. Pick a place you trust.

Please do not email us your export file. If you do, we will delete it.

Reminders

If you turn on reminders, the app schedules notifications on your phone. They are made and shown by your phone. They do not use our servers or a push service. The app asks for notification permission and works without it.

By default the text of a reminder is neutral, so it does not reveal anything on your lock screen. You can change that in Settings.

Purchases

Some features need Period Vault Plus. The basic tracking is free.

You buy Plus through the Apple App Store or Google Play. Apple or Google takes the payment and handles the receipt. They have their own privacy policies. We do not see your name, your card or your Apple or Google account. Your phone tells the app that Plus is on, and the app unlocks the features.

The app has no other connection to a payment provider. There is no analytics or billing company in between.

Apple and Google give us sales reports. These can include things like the country where a purchase was made. They also give us crash and performance reports from users who agreed to share them with developers in their phone settings. Those reports do not contain your entries.

If you ask Apple or Google for a refund or cancel a subscription, you do that with them.

Support emails

If you write to support@periodvault.com, we get your email address and what you write. We use it to answer you. The legal basis is our legitimate interest in helping you, or your request to us. We keep it for up to 12 months after the last message, then delete it. An email provider stores it for us and may process it outside your country. We do not use it for anything else.

Please do not send us health details. We do not need them to help you.

Do we sell or share your data?

No. We do not sell your data. We do not share it for advertising. We have no cycle data to share.

Law enforcement and other requests

We hold no cycle data. We have no account for you and no copy of your entries. If we receive a legal request, we can only give what we have. That is support emails if you sent any, and the sales and crash reports Apple and Google give us. Apple and Google hold their own records of purchases. A request for those has to go to them.

If a request asks for health data we do not hold, we will say so.

Consumer health data (Washington, Nevada, Connecticut and other US states)

Some US states have laws about "consumer health data", including information about reproductive health. Period Vault does not collect, share or sell consumer health data. Your entries stay on your phone. We have no access to them. You control them. You can see, change, export and delete them in the app.

How long we keep things

• Cycle data: it lives on your phone until you delete it or uninstall the app.
• Export files: you control them.
• Support emails: up to 12 months after the last message.

Deleting your data

Open Settings and choose Delete all data. The app removes your entries, your settings and your scheduled reminders from your phone. This cannot be undone. Nothing is left on our side because we never had it.

Uninstalling the app also removes your entries from that phone.

Exports you made earlier are not touched. Delete those files yourself from where you saved them. Purchase records at Apple or Google stay with them.

Your rights

Your cycle data is on your phone, under your control. You can see it, change it, export it and delete it in the app. That covers access, correction, portability and erasure.

For anything we do hold, such as a support email, you can ask us to show it, fix it, give you a copy or delete it. Write to support@periodvault.com. We answer within 30 days.

If you live in the EU, Norway, Switzerland, Canada or a US state with a privacy law, you may have more rights. We honour them. If you think we handled your data wrongly, you can complain to your data protection authority. In Switzerland that is the FDPIC. In Norway it is Datatilsynet. In Canada it is the Office of the Privacy Commissioner. In Germany it is the authority of your state. In the EU you can also complain to the authority in the country where Valdemar Kobelis is based.

Who is responsible

For the small amount of data we hold, such as support emails, Valdemar Kobelis is the controller. Contact details are at the top of this page.

Because your cycle data never reaches us, you are the only one who controls it.

Children

Period Vault is for people aged 13 and older. It is not made for children under 13. The app itself collects no personal information. We only get personal information if you write to us. If we learn that a child under 13 wrote to us, we delete the message. If you are under 18, ask a parent or guardian before you buy a subscription.

If you are a parent and think your child under 13 uses the app, write to us. We hold nothing about the app use, and we will help you delete the support emails.

Security

Your data is protected by the lock and encryption of your phone. You can also turn on an app lock in Settings. Keep your phone's software up to date. Choose a strong passphrase for exports.

We do not run a server that could be breached. If we learn of a problem that could expose your data, we will release an update. We will tell you in the app and on our website.

Medical notice

Period Vault is not a medical device. It does not give medical advice. It is not birth control. Its estimates can be wrong. Talk to a doctor about your health.

Changes to this policy

If we change this policy, we will update the date at the top. If a change affects how your data is handled, we will tell you in the app before it takes effect. We will never start collecting your cycle data without asking you first.
