These terms

These terms are the agreement between you and Cloudy NI (sole trader), the publisher of PeriLog (Android package com.luckytools.perimenopause_tracker). Installing or using the app means you accept them; if you do not accept them, do not use the app.

They cover the app and the cloudyni.com pages that support it, including the privacy policy. That policy explains what the app does with your information; these terms explain what you may and may not do with the app, and what we are responsible for.

Your licence to use the app

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the app on devices you own or control, for your own private use, for as long as these terms are in force.

You must not:

• copy, sell, rent, sublicense or redistribute the app, or make it available to anyone else;
• modify the app or create a derivative work from it;
• reverse engineer, decompile or try to extract source code, except to the extent that the law says the restriction cannot apply;
• remove or hide our notices, branding or attribution;
• use the app to break the law, to infringe anyone's rights, or in a way that breaks Google Play policy.

Google Play

The app is distributed through Google Play, so Google Play Terms of Service apply to you as well, and Google's own policies govern the store, the download and the payment.

Google is the merchant of record for anything you buy inside the app: it takes the payment, keeps the billing record, and handles refunds and billing disputes under its own policy. If your use of the app breaks Google Play's rules, Google can act against your Google account as well, which is outside our control.

Free tier, advertising and paid products

PeriLog is free to download and supported by advertising. Optional Premium is sold through Google Play Billing as an auto-renewing monthly subscription, alongside a one-time lifetime purchase that does not renew.

Premium removes advertising and extends trend history to the full 90-day view. Two products are offered: a monthly subscription that renews until you cancel, and a lifetime purchase that is paid once and never renews. The Google Play purchase sheet — not this page and not any marketing page — states the price, the billing period and whether the product renews.

The free version contains banner and interstitial advertising served by Google AdMob, with consent collected through Google's User Messaging Platform where required. Premium removes advertising for the period you have paid for — permanently, in the case of the lifetime product.

The product identifiers the app requests from Google Play are:

• premium_monthly — auto-renewing monthly subscription
• premium_lifetime — one-time purchase, no renewal

The product identifiers below are the ones the app requests from Google Play. The price is deliberately not fixed on this page: Play is the merchant of record and the amount you pay is always the amount shown on the Google Play purchase sheet when you confirm, including any local tax. Treat the price on that screen as the authoritative one.

These rules apply to every purchase:

• Auto-renewal. If the product you buy is a subscription it renews automatically at the end of each billing period, at the price shown in Google Play, until you cancel. If the product is a one-time purchase it does not renew.
• Cancelling. Cancel in Google Play → Payments & subscriptions → Subscriptions. Uninstalling the app does not cancel billing. You keep the paid features until the end of the period you have already paid for.
• Refunds. Google is the merchant of record, so refunds and billing disputes are handled by Google under Google Play policy, not by us. We cannot issue, block or reverse a Google Play charge.
• Price changes. We do not set the amount you are charged — Play does, and it shows the exact price (including tax) before you confirm. If a subscription price changes, Play notifies you and asks you to accept it before it applies.
• Restoring a purchase. Reinstalling the app and signing in with the same Google account restores an active entitlement. If it does not appear, use Restore purchases in the app, then contact support.

Optional encrypted cloud backup

Cloud backup is optional and off by default. PeriLog is complete without an account — every feature works with your data on the phone. If you choose Settings → Cloud backup & sync and create an account, your logs are encrypted on your device with AES-256-GCM using a key derived from your password (PBKDF2-HMAC-SHA256, 120,000 iterations). Only that ciphertext leaves the phone: your account holds one encrypted backup record, and the key stays in this device's secure storage. Authentication and storage are provided by Supabase, our processor, with the project hosted in the United Kingdom (London, eu-west-2).

Because your password is what decrypts the backup, we cannot read it, we cannot recover it for you, and a password reset cannot unlock an older backup. Signing in on another device with the same email and password restores the same encrypted data. Signing out removes the local key. One encrypted row per account is all that exists server-side — there is no readable copy, no analytics copy and no second database.

If you choose to use that optional feature, these rules apply:

• Your logs are encrypted on your device before upload. The server stores ciphertext it cannot read, and so can we.
• A forgotten backup password cannot be recovered by us and the backup cannot be decrypted without it. There is no master key and no reset. Do not treat cloud backup as your only copy of anything you cannot afford to lose.
• The backup is a convenience, not a medical record. Do not rely on it for clinical purposes, and keep your own exports (the app can write a JSON backup file or a PDF report) if the data matters to you.
• You may delete the account and its encrypted backup at any time — from inside the app or by asking us. We complete verified deletions within 30 days.

Deleting the account deletes the stored backup with it. Both routes — the in-app one and the email one — are set out on the data deletion page.

Acceptable use and your responsibilities

You are responsible for how you use the app, for anything you enter, send or save in it, and for keeping your device and your account secure. Keep your own copy of anything you cannot afford to lose, and where the app can export or share your data, use it.

Do not try to interfere with the app, its servers or other users, do not try to unlock a paid feature without paying for it, and do not use the app in a way that breaks the law.

On the free tier, advertising is part of how the app is paid for. If you would rather not see it, buy the paid product or uninstall the app.

If you create an account, keep your password to yourself. Anything done through your account is treated as done by you, so tell us straight away if you think somebody else has access to it.

Content and ownership

The app itself, its design, its text, its icon and our branding belong to us or to our licensors, and nothing in these terms transfers any of that to you.

Anything you write, record, scan, photograph or save in the app stays yours. We claim no ownership over it, and where it never leaves your device we never even see it.

Where the app includes reference material supplied by someone else — a published text, a public dataset, a third-party image or a calculation method — that material stays the property of its supplier, and the limitations below explain what it can and cannot be used for.

Important limitations

• Not medical advice and not a medical device. PeriLog is a self-tracking notebook. It does not diagnose, treat, cure or prevent any condition, it is not a contraceptive, and it cannot tell you whether you are fertile, pregnant or menopausal.
• Predictions are estimates, not facts. Cycle and symptom predictions are calculated from the dates you enter. They can be wrong, and they are not a substitute for clinical assessment, diagnosis or testing.
• No emergency use. The app has no alarm, no monitoring and nobody watching the data. In an emergency, contact your local emergency number.
• You decide what to record. Only log what helps you. You are in control of what you write down, and everything can be deleted from the app.
• Do not rely on cloud backup for anything critical. Because the backup is encrypted with your password, a lost password means a lost backup, and we cannot restore it for you.

These limitations are part of the app's design rather than small print added afterwards. If one of them rules out the way you need to use the app, then the app is not the right tool for that job, and you should not rely on it.

Our liability

Nothing in these terms limits a right you have as a consumer that cannot be limited, and nothing here excludes our liability for death or personal injury caused by our negligence, for fraud, or for anything else the law does not allow us to exclude.

Subject to that, the app is provided as it is. We do not promise that it will be uninterrupted or error-free, or that it will suit a particular purpose, and we are not liable for indirect or consequential loss, for lost data, or for loss that was not reasonably foreseeable when you started using the app.

Subject to the first paragraph above, our total liability for any claim connected with the app is limited to the amount you paid for the app in the twelve months before the event that gave rise to the claim.

If you are a consumer in the UK, the Consumer Rights Act 2015 gives you rights against us and against Google, and these terms do not reduce them.

Changes to the app and to these terms

We may update the app and these terms. This is the current version, dated 30 September 2026. If we change the terms in a way that matters we will update this page before the change takes effect, and continuing to use the app after that means you accept the new version.

We may also change, suspend or withdraw the app, or a feature in it. If we withdraw something you have already paid for, we will deal with that in line with Google Play's policies and with your consumer rights.

Ending this agreement

You can end this agreement at any time by uninstalling the app and, if you created an account, deleting it as the data deletion page describes. Cancelling a subscription is separate and is done in Google Play.

We may end this agreement if you seriously break these terms. Where we do, we will tell you what happens to any account you hold, and the sections on your licence and on our liability continue to apply.

Governing law

These terms are governed by the law of Northern Ireland, and disputes may be brought in the courts of Northern Ireland. If you live elsewhere in the United Kingdom you can also bring a claim in your own courts, and nothing here stops you using a consumer advice service, a regulator or an alternative dispute-resolution scheme.
