Terms of Use

These terms govern your use of the 5n1k mobile app (the “App”), published by [ŞİRKET UNVANI] (“4wise”, “we”). By downloading or using the App you accept these terms. How we handle personal data is described in the Privacy Policy.

1. The App

5n1k is a reading app that tells what happened on this day in history through the cultural memory of the country you choose, and lets you read the same event through other countries' eyes. We may change, improve or remove content and features over time.

2. Your account

• You need to sign in with Apple or Google to use the App. You must be at least 13; if you are a minor where you live, you need a parent's or guardian's consent.
• Your account is personal. It can stay signed in on at most two devices at a time.
• You can delete your account at any time under Settings → Your account → Delete account (details).
• We may suspend or close accounts that seriously breach these terms.

3. Premium, subscriptions and purchases

• Part of the App is free. Premium is offered as a monthly or yearly auto-renewing subscription, or as a one-time “lifetime” purchase. Current prices are shown in the App, in your store's currency, before you buy.
• Purchases are made through the Apple App Store or Google Play and charged to your store account. The store's own terms also apply.
• Auto-renewal: a subscription renews automatically for the same period and price unless cancelled at least 24 hours before the end of the current period; the renewal is charged within the 24 hours before the period ends. If a free trial is offered, it converts to a paid subscription unless cancelled before the trial ends.
• Cancelling: you can cancel only through the store — on iPhone, Settings → [your name] → Subscriptions; on Android, Google Play → Profile → Payments & subscriptions → Subscriptions. Cancellation takes effect at the end of the current period, and Premium stays on until then. Deleting your account does not cancel a subscription.
• Lifetime: a one-time payment that does not renew; it gives Premium access for as long as the App is offered.
• Refunds: refunds are handled by the stores — for Apple at reportaproblem.apple.com, for Google Play through Google Play's refund process. Your statutory consumer rights are not affected.
• To move a purchase to a new device, use Restore purchase in the App.

4. Apple users

For the iOS app, Apple's standard Licensed Application End User License Agreement (EULA) applies in addition to these terms; in case of conflict, the mandatory provisions of Apple's EULA prevail. Apple is not a party to these terms and is not responsible for maintaining or supporting the App.

5. Content and intellectual property

• The texts, design, brand and software of the App are ours or licensed to us. We grant you a non-transferable, non-exclusive licence to use the App for personal, non-commercial purposes.
• Media such as photos, films and audio belong to their respective rights holders; most are in the public domain or under Creative Commons licences, and each item's source and licence is credited in the App. You may use those items under their own licence terms.
• You may share individual stories personally with the share feature; bulk copying, republishing or selling the content is not allowed.

6. Acceptable use

You may not scrape content in bulk with automated tools, try to bypass security or disrupt our systems, use someone else's account, share or resell Premium access, reverse engineer the App (except where the law expressly allows it) or use the App for unlawful purposes.

7. About historical content

We write the stories from public sources, with AI assistance and editorial review. Although we work carefully, historical content can contain errors, omissions or contested interpretations, and different countries' perspectives deliberately carry different emphasis. The content is general information and no substitute for academic or legal sources. If you spot a mistake, write to support@5n1k.io — we welcome corrections.

8. Limitation of liability

The App is provided “as is”; we do not guarantee it will be uninterrupted or error-free. To the extent permitted by law, we are not liable for indirect damages or loss of data or profit, and our total liability is limited to what you paid us for the App in the 12 months before the claim. This limitation does not apply to intent, gross negligence, injury to life or health, or liability that cannot be excluded under consumer law.

9. Governing law and disputes

These terms are governed by the laws of the Republic of Türkiye. The courts and enforcement offices of [ŞEHİR] have jurisdiction. As a consumer you keep your right to apply to Consumer Arbitration Committees and consumer courts, and the mandatory consumer protection rules of the country you live in.

10. Changes

We may update these terms. We announce material changes in the App before they take effect; continuing to use the App afterwards means you accept the new terms.
