Privacy Policy

Last updated: 11 October 2026

The Crossify101 app collects no data. Truly nothing. This website sets no cookies and has no analytics, ads or trackers. The only personal data involved are the technical server logs our host keeps when you visit, and anything you choose to send us by email.

Who is responsible

This policy covers the Crossify101 app (for iPhone, iPad, Mac and Android) and this website, crossify101.com. Both are published by Mourad Ghafiri, a private individual, who is responsible (the “data controller”) for the small amount of personal data described below. You can reach him at contact@crossify101.com.

The Crossify101 app

What we collect

Nothing. Crossify101 does not collect, transmit, sell, rent or share any personal information or usage data. We do not see, receive or have any access to information about you.

No network access

The application has no networking layer on its runtime path — it is technically unable to contact any server. On Android, the app does not even declare the INTERNET permission. Everything you see and play is bundled inside the app and runs entirely offline.

No permissions

Crossify101 requests no device permissions whatsoever: no camera, no microphone, no location, no contacts, no storage, no notifications. You can confirm this in your device settings — the app's permission list is empty.

No tracking or advertising

There are no analytics SDKs, no advertising networks, no attribution or marketing trackers, and no crash-reporting services. No advertising identifier is read or used.

Where your progress lives

Your game progress — solved levels, point totals and language preference — is stored only on your device, inside a single sandboxed file that belongs to the app. It never leaves the device. On both iOS and Android, automatic cloud backup and device-to-device transfer of this file are disabled, so your progress is not copied to any cloud service.

Because everything is local, deleting the app removes all of its data. We have no copy of it and cannot recover it for you.

Purchases

Crossify101 is free and contains no in-app purchases, subscriptions or paid content. The in-game "points" are a local game mechanic only and have no monetary value.

This website

No cookies, no tracking

This website sets no cookies and stores or reads nothing on your device (no local storage, no fingerprinting). It has no analytics, no advertising, no social-media buttons and no embedded third-party content. Fonts, images and scripts are all served from this site itself, so opening a page sends nothing to Google or any other third party. That is why there is no cookie banner: there is nothing to consent to.

The only possible exception comes from our host’s security systems, not from our pages. If Cloudflare suspects a visit is automated, it may show a short check and then store a cookie (cf_clearance) recording that you passed it. Cloudflare classifies this cookie as strictly necessary for security. It is not used for tracking or advertising.

Server logs kept by our host

Whenever a browser requests a web page, the server automatically receives some technical information. Ours is no exception. Our hosting provider, Cloudflare, Inc. (United States), receives your IP address, the date and time, the page requested, your browser’s user agent and the referring page. Cloudflare processes this on our behalf, as our processor, to deliver the site and protect it against abuse and attacks. We do not use this data to identify, follow or profile you, and we do not combine it with any other data.

Links to the app stores

The download buttons link to Apple’s App Store and Google Play. Nothing is loaded from those stores until you click. Once you are on their pages, Apple’s and Google’s own privacy policies apply.

When you email us

If you write to contact@crossify101.com, we receive your email address, your name if you include it, and your message. We use them only to reply to you, based on our legitimate interest in answering your message (GDPR Article 6(1)(f)). Our email provider stores the messages on our behalf. We keep a conversation only as long as needed to handle your request and delete it no later than 12 months after our last exchange, unless the law requires us to keep it longer. Please do not send sensitive information by email.

Sharing and transfers

We do not sell, rent or share personal data. We do not use it for advertising or profiling, and no automated decisions are made about you. The only recipients are the service providers described above (website hosting and email), which act on our instructions.

Cloudflare is based in the United States and runs servers worldwide, so server-log data may be processed outside your country. For data leaving the European Economic Area, the United Kingdom or Switzerland, Cloudflare relies on its certification under the EU-U.S. Data Privacy Framework (and its UK and Swiss extensions), with the European Commission’s standard contractual clauses as a fallback.

Your rights

Wherever you live, you can ask us what personal data we hold about you and ask us to correct or delete it. Email contact@crossify101.com and we will reply within one month. We hold almost nothing: the app sends us no data, and server logs do not identify you by name. So tell us what you are looking for, and we will help as far as we can.

Europe (GDPR)

If you are in the European Union, the European Economic Area or the United Kingdom, you have the right to access your data, have it corrected or erased, restrict its use, object to its use (including use based on our legitimate interest), and receive it in a portable format. You can also complain to your data protection authority. In France, this is the CNIL (cnil.fr). French residents can also give instructions on what should happen to their data after their death.

United States

We do not sell or share personal information, and we do not use it for targeted advertising. Because this site does no tracking at all, it behaves the same whether or not your browser sends a “Do Not Track” or Global Privacy Control signal: there is nothing to switch off. No third party collects information about your activity across websites through this site.

China

If you are in mainland China, the Personal Information Protection Law gives you the right to know about and decide on the processing of your personal information, to restrict or refuse it, to access, copy, correct or delete it, and to ask us to explain these rules. To use these rights for data held by us or by Cloudflare (whose role, purpose and data are described above), email us at the address below.

Children’s privacy

Crossify101 is rated suitable for all ages and is safe for children. As the app collects no data at all, it collects no data from children either. The website is designed for a general audience and asks no one for any information. Technical data such as IP addresses is used only to deliver and secure the site, never to contact, profile or advertise to anyone, and we do not knowingly collect personal information from children. If you believe a child has emailed us, a parent or guardian can ask us to delete the message and we will do so.

Changes to this policy

If this policy ever changes, the updated version will be posted on this page with a new "last updated" date.
