Privacy Policy
This Privacy Policy explains how The Puzzle Loft handles information when you use our website, play web games, or use the Flipudoku mobile app.
Last updated: 11 December 20251. Who we are and what this covers
The Puzzle Loft is a puzzle brand operated by Evrenna, a small independent company based in Belgium. For data protection purposes, Evrenna is the data controller for The Puzzle Loft.
1.1 Scope
This Privacy Policy applies to:
- The website thepuzzleloft.com and its web games (for example Classic Sudoku and Flipudoku in the browser).
- The Flipudoku mobile app and any future mobile apps released under “The Puzzle Loft” by Evrenna.
This Policy does not apply to third-party websites, app stores, or services that we do not control, even if you access them through links from our website or apps.
2. Information we collect
We aim to collect as little personal data as reasonably possible. The types of information we may process fall into the categories below. Not all categories will apply to every user.
2.1 Basic identifiers
Depending on how you use our services, we may process:
- IP address and approximate region (for example, country or city level).
- Internal identifiers such as an app user ID or session ID.
- Advertising identifiers on mobile devices (for example, Apple’s IDFA or Google’s Advertising ID), if used for ads.
2.2 Device and technical information
To keep our services secure, debug issues, and understand performance, we may collect:
- Device type and model, operating system and version, language, and time zone.
- Screen size or resolution and app/browser version.
- Connection details such as network type and basic performance metrics.
2.3 Usage information
We may process information about how you interact with the website and app, for example:
- Pages visited and buttons tapped on the website.
- Which game modes you open (for example, Classic Sudoku vs Flipudoku).
- Session length, approximate time spent in the app or on a page.
- Game progress or completed puzzles, where this is technically collected.
2.4 Purchase and store information
If you make in-app purchases in the Flipudoku app or buy our books via external stores, those transactions are processed by third-party platforms (such as Apple, Google, Amazon, or others). We may receive limited information such as:
- Confirmation that a purchase or subscription was successful.
- The product identifier and region of purchase.
We do not receive your full payment card details from these platforms.
2.5 Communication and support
If you contact us directly (for example by e-mail), we may process:
- Your name or nickname, if you choose to share it.
- Your e-mail address and the content of your message.
- Any screenshots or files you voluntarily provide.
2.6 Cookies and local storage
The website may use cookies, local storage, and similar browser technologies to remember simple preferences and keep things running smoothly. Examples include:
- Your chosen theme (dark, light, or system).
- Future local preferences, such as default difficulty or game options.
This information is normally stored on your own device and is not automatically sent to us as personal data unless combined with other information.
3. Where we get information from
We obtain information from several sources:
- Directly from you – for example, when you send us an e-mail or choose to submit feedback.
- Automatically – for example, through your browser or device when you access the website or app (IP address, device type, crash logs, usage events).
- From platforms and partners – for example app stores (purchase confirmations, ratings) or analytics/advertising providers, if used.
- From publicly available sources – for example public reviews or comments on app stores or social media.
4. How we use information and legal bases
We use the information described above for the purposes below. Under EU data protection law, we must also identify a legal basis for each category of use.
4.1 Providing and maintaining the services
We process data to:
- Deliver the website, web games, and app functionality you request.
- Ensure the content is displayed correctly on your device.
- Save basic preferences and remember your choices locally.
Legal basis: performance of a contract (providing the service you use) and legitimate interests.
4.2 Security, fraud prevention, and stability
We may use technical and log data to protect our services and users, for example to:
- Detect and prevent abuse, cheating, or malicious traffic.
- Monitor uptime, crashes, and server performance.
- Diagnose and fix bugs and compatibility issues.
Legal basis: legitimate interests in keeping services secure and reliable; legal obligations where applicable.
4.3 Analytics and improvement
We may use analytics tools (either built-in or from third parties) to understand how people use the website and app. This can include:
- Counting unique installs or visitors in broad terms.
- Understanding which screens, modes, or features are used most.
- Seeing crash rates or funnel steps to improve usability.
Where required by law (particularly in the European Economic Area and UK), we will ask for your consent before using non-essential analytics or tracking technologies.
Legal basis: legitimate interests in improving our services; consent where required.
4.4 Advertising and monetization (Flipudoku app)
The Flipudoku mobile app may use advertising to support development and keep the app affordable or free to use. This may involve integrating mobile advertising SDKs, such as Google AdMob or similar providers.
These partners may process data such as:
- Mobile advertising identifiers (IDFA, AAID or similar).
- Approximate location, device type and language.
- Information about interactions with ads (views, clicks, rewarded videos).
Where required by law, we will ask for your consent before showing personalized advertising or using certain profiling features. You can usually control advertising permissions using:
- In-app privacy or ad settings, if available.
- Your device settings for ad tracking and personalized ads.
Legal basis: consent where needed; otherwise legitimate interests in monetizing and maintaining the service.
4.5 Communication and support
If you contact us, we will use your information to respond to your request, fix issues, or follow up on feedback and bug reports.
Legal basis: performance of a contract (supporting the service) and legitimate interests.
4.6 Legal compliance
In some cases, we may need to process or retain information to comply with legal obligations, respond to lawful requests, or enforce our rights.
Legal basis: compliance with legal obligations; legitimate interests.
5. Cookies, local storage, and mobile SDKs
5.1 Website cookies and local storage
The website may use cookies and local storage for purposes such as:
- Remembering theme and visual preferences.
- Keeping basic technical settings so the site behaves consistently.
You can manage or delete cookies via your browser settings. If you block all cookies, some parts of the website may not function as intended.
5.2 App SDKs and similar technologies
The Flipudoku app may use third-party software development kits (“SDKs”) for analytics, crash reporting, or advertising. These SDKs can be conceptually similar to cookies but run inside the app instead of the browser.
Each provider has its own privacy notice describing exactly how it processes data. We aim to work only with reputable partners who follow applicable privacy laws.
6. How we share information
We do not sell lists of players or subscribers in the traditional sense. We may share information in the situations below:
6.1 Service providers
We use third parties to help us operate and improve The Puzzle Loft, such as:
- Hosting providers and server infrastructure.
- Crash reporting and analytics tools.
- Advertising networks and mediation partners.
- Payment and app store platforms.
These third parties are expected to process data only as needed to provide their services to us and under appropriate confidentiality and data protection safeguards.
6.2 Advertising partners
When we use advertising in the Flipudoku app, certain data (such as your advertising ID, device information, and interaction with ads) may be shared with advertising partners so they can technically deliver ads and, where allowed, personalize them.
6.3 Legal and safety
We may disclose information if we believe it is reasonably necessary to:
- Comply with a law, regulation, legal process, or government request.
- Protect the safety, rights, or property of The Puzzle Loft, our users, or the public.
- Enforce our terms or investigate possible violations or fraud.
6.4 Business transfers
If we are involved in a merger, acquisition, asset sale, or similar business change, information may be transferred as part of that transaction, subject to applicable law.
6.5 With your consent or at your request
We may share information with third parties when you explicitly ask us to, or when you consent to additional sharing through a specific feature.
7. International data transfers
The Puzzle Loft is operated from the European Union, but some of our service providers may be located in other countries. This can involve transferring data outside the EU/EEA or your home country.
When we transfer personal data internationally, we aim to rely on appropriate safeguards, such as:
- Adequacy decisions by the European Commission.
- Standard contractual clauses approved by the European Commission.
These measures are intended to ensure that your data receives a similar level of protection as in your home jurisdiction.
8. Your rights and choices
Your privacy rights depend on where you live. The list below summarizes common rights under the EU General Data Protection Regulation (“GDPR”) and similar laws.

Data stored locally on your device via cookies or local storage remains there until you clear it via your browser or device settings.
