Privacy policy

Learn about our privacy practices and your rights.

We want you to feel comfortable on crumbs.gg (our “website”) and not have to worry about the security of your data. That is why data protection is an important part of our corporate philosophy. In this Privacy Policy, you will find all the information about which Personal Data we collect and process and for what purpose. Equally, we will also inform you of your data protection rights and how you can assert them.

General Principles

What is Personal Data?

Personal Data is “any information relating to an identified or identifiable natural person”. This includes, for example, name or address data, telephone number, mobile number, or online identifiers such as your device id and your IP address.

What is processing?

“Processing” means any operation or set of operations which is performed upon Personal Data, whether or not by automatic means. The term is broad and covers virtually any handling of data.

Who is responsible for data processing?

The responsible party for data processing is Crumbs GmbH, Hagenholzstrasse 68., 8050 Zürich, Switzerland (“Crumbs”, “we”, “us”, or “our”). If you have any questions or if you wish to exercise your rights, please contact us by email using support@crumbs.gg or write to us at the above address.

What law applies?

Our use of your Personal Data is subject to both the Swiss Federal Data Protection Act, as amended (“nDSG”) and the EU’s General Data Protection Regulation (“GDPR”), and of course we process your Personal Data accordingly. Further and under consideration that the nDSG has been modeled on the basis of the GDPR, no conflict should arise pursuing a uniform approach. However, should ambiguity occur the most stringent provision is chosen to ensure the most comprehensive approach when it comes to protecting your personal data. The association SwissPrivacy. Law has published a comparison table between the nDSG and the GDPR which can be consulted by visiting here.

What are the Legal Bases for processing Personal Data

In accordance with the nDSG and the GDPR, we have to have at least one of the following legal bases to process your Personal Data: a) you have given your consent, b) the data is necessary for the fulfillment of a contract / pre-contractual measures, c) the data is necessary for the fulfillment of a legal obligation, or d) the data is necessary to protect our legitimate interests, provided that your interests are not overridden.

Who is the competent data protection authority?

The supervisory authority in Switzerland is: The Swiss Federal Data Protection and Information Commissioner, Feldeggweg 1, CH-3003 Bern, Switzerland, www.edoeb.admin.ch.

How long will you keep my data?

We process and store your Personal Data only for the period of time required to achieve the respective processing purpose or for as long as a legal retention period exists (in particular commercial and tax law in accordance with Switzerland's Commercial Law and Fiscal Code and others for up to 8 years). Once the purpose has been achieved or the retention period has expired, the corresponding data is routinely deleted.

What Personal Data do we process?

The personal data we process depends on how you choose to interact with our services, specifically whether you play as a guest or create an optional account.

Technical Data

When you access our website, some access data is recorded automatically and stored in a log file on our website's server. This means if you browse and simply have a look at our website, we process a) the IP address of your computer, b) the date and time of your access, c) the name and URL of the accessed file, d) the browser used, e) the amount of bytes transferred, f) the status of the page request, g) the session ID and g) the referrer URL. The legal basis for processing is our legitimate interest.

Hosting of our website

We use the hosting services of Vercel Inc, for the purpose of hosting and displaying our website. Vercel does so on the basis of processing on our behalf, and that also means that all data collected on our website is processed on Vercel's servers. The basis for processing is our legitimate interest, and the initiation and/or fulfillment of a contract.

Cookies

We use so-called cookies on our website. Cookies are pieces of information that are transmitted from our web server or third-party web servers to your web browser and stored there for later retrieval. Cookies may be small files or other types of information storage. There are different types of cookies: i) Essential Cookies. Essential cookies are cookies to provide a correct and user-friendly website; and ii) Non-essential Cookies. Non-essential Cookies are any cookies that do not fall within the definition of essential cookies, such as cookies used to analyze your behavior on a website (“analytical” cookies) or cookies used to display advertisements to you (“advertising” cookies). As set out in Switzerland's Unfair Competition Act (as amended) (“UCA”), the Telecommunications Act (as amended) (“TA”) and the EUs Privacy and Electronic Communications Directive (“PECD”), we need to obtain consent for the use of Non-essential Cookies. For further information on the cookies we use, please refer to our Cookie Policy. The legal basis for processing is our legitimate interest and your consent.

Cookie consent

Our website uses a cookie consent tool to obtain your consent to the storage of cookies and to document this consent. When you enter our website, the following Personal Data is transferred to us: a) Your consent(s) or revocation of your consent(s); b) Your IP address; c) Information about your browser; d) Information about your device; d) Time of your visit to our website. The basis for processing is our legitimate interest and your consent.

Economic analyses and market research

For business reasons, we analyze the data we have on web and server traffic patterns, website interactions, browsing behavior etc. The analyses serve us alone and are not disclosed externally and processed using anonymous analyses with summarized and or anonymized values. For this purpose we use Hotjar (Hotjar Ltd) and PostHog (PostHog Inc). The legal basis is our legitimate interest and your consent. For further information on our use of HotJar and PostHog, please refer to our Cookie Policy.

We also use Google Analytics (a service of Google LLC) to analyze website traffic and user behavior. Google Analytics collects data such as your IP address (which is anonymized before storage), page views, session duration, and the browser and device you are using. We use these insights to improve our website's functionality and user experience. The legal basis for this processing is your consent, which we obtain through our cookie consent tool, and our legitimate interest in understanding how our services are used.

Furthermore, for internal business intelligence and to better understand how our services are used, we utilize Metabase, an open-source analytics tool. We host this tool ourselves on cloud infrastructure provided by DigitalOcean. By self-hosting this tool, we maintain control over the data processed within it, which may include your account and usage data, to generate aggregated and anonymized reports for improving our services.

Contacting us and using our services

You can contact us in various ways and data is always collected in the process. You provide us with most of the data that we process when you contact us such as your name, and email address. This data is collected and processed exclusively for the purpose of contacting you and processing your request and then deleted again, provided that there is no legal obligation to retain it. We process the personal data that arises when you use our services in order to provide our contractual services. In particular, this includes our support, correspondence with you, invoicing, fulfillment of our contractual, accounting and tax obligations. Accordingly, the data is processed on the basis of the fulfillment of our contractual obligations and our legal obligations. Lastly, we process data in the context of administrative tasks as well as organization of our operations, financial accounting and compliance with legal obligations, such as archiving. In this regard, we process the same data that we process in the course of providing our contractual services. The purpose and our interest in the processing lies in the administration, financial accounting, office organization, archiving of data, i.e., tasks that serve the maintenance of our business activities, performance of our tasks and provision of our services. The legal basis for processing the above is our legitimate interest, the provision or initiation of a contractual service and your consent.

Playing a Game & Optional Account Creation

Creating an account is entirely optional to play our games. We process different data depending on whether you play as a guest or create a permanent account.

1. Playing as a Guest

To play a game without creating an account, you only need to provide a nickname. We do not require your name, email address, or any other personal details. This nickname is used to identify you within your current game session.

Please note that when you play, we still process the necessary technical data to run the game and maintain the connection, as described in the "Technical Data" section. The legal basis for processing your nickname and technical data in this context is the fulfillment of our contractual obligation to provide the game service to you.

2. Creating an Account (Optional)

You have the option to create a permanent account to save your game progress and maintain a consistent identity across sessions. To register, you can provide your Full Name, Email address, and a chosen password.

Alternatively, you are able to sign up using the convenience login from Google or Apple. For this, you will be asked to provide your basic information (i.e., name, email address, and display picture) linked to your account. When registering via Google's or Apple's connect function, you agree to their relevant terms and consent to this data being transferred to us.

The legal basis for creating and maintaining your account is the fulfillment of our contractual obligation to you and your consent. This processing is necessary to provide account-specific services and to authenticate users when accessing sensitive information, for instance, when game creators manage their games and bookings.

Optional Image-Based Game Features

To enhance your gameplay, we offer interactive features that may require access to your device's camera or photos. These could include selfie challenges, object-finding hunts, or other creative picture-based riddles.

Participation in these features is entirely optional, and you can skip them without affecting your ability to complete the main game. To use these features, your web browser will prompt you for permission to access your camera or photos. You can manage or revoke this permission at any time through your browser's site or privacy settings.

Your Responsibility for Image Content: By choosing to use these optional features, you are responsible for the content you capture or upload. If you use an image that includes other identifiable individuals, you confirm that you have obtained their explicit permission for their image to be collected, processed, and temporarily stored by us for the purpose of the specific game feature.

Our Data Handling Process: Any image you provide is used exclusively for the game feature you have chosen to use. Depending on the feature, this may involve:

  • Processing a live camera stream without storing the images on our servers.
  • Temporarily storing an uploaded image file on our secure servers for processing. For optimization, we may process images through our partner (images.weserv.nl).

The digital file is not shared with other users and is not accessible online without having access to its unguessable URL. They may be used to generate temporary in-game effects or physical keepsakes (e.g., a printout), as described in the feature.

Strict Data Deletion and Minimization: We are committed to data minimization. For features that require temporary storage, your uploaded digital image is permanently deleted from our systems and our partner's systems within 14 days after your game session concludes. For features that process a live camera stream, the images are not stored by us. We do not retain digital copies of your photos beyond the period essential for the feature's operation.

Location-Based Game Features

Some of our riddles and game features require your device's real-time location to verify that you have arrived at a specific physical spot.

Optional and Consent-Based: If a game includes these features, immediately before the first location based riddle, we will ask for your consent to access your device's location services for the duration of that game session. You can decline without affecting your ability to play the rest of the game. You can also revoke this permission at any time through your device's system settings.

How We Use Location Data: Our game interacts with your device's location services solely to confirm if you are within the designated area to solve a task. We do not receive or store a continuous stream of your GPS coordinates, nor do we track your movements outside the context of solving a riddle.

No Storage of Location Data: This location data is used for the immediate purpose of solving the riddle and is not stored or saved on our servers.

Third-Party Services: This functionality is powered by Google Maps technology. When you consent to use a location-based feature, your interaction is also governed by the Google Maps/Google Earth Additional Terms of Service and Google's Privacy Policy.

Microphone-Based Game Features

Certain riddles in our games may require access to your device's microphone to be solved.

Optional and Consent-Based: These features are entirely optional. We will always ask for your explicit consent before accessing your microphone. You can decline without impacting your ability to play the rest of the game.

How We Use Audio Data: We use microphone access in two ways: 1. Real-time Sound Analysis: For some riddles, such as a singing task, our game may analyze audio from your microphone in real-time to detect properties like musical pitch or loudness. This audio is processed for the immediate purpose of the riddle and is not recorded or stored. 2. Voice Message Analysis: For other riddles, you may be asked to record a short voice message. This audio recording is securely sent to our service provider, OpenAI, which analyzes the content to verify if it meets the riddle's requirements.

Strict Data Deletion: In the case of voice messages sent for analysis, the audio file is permanently deleted from our systems and our partner's systems immediately after the analysis is complete. We do not retain voice recordings.

Service offers of third-party providers

We use service offers of third-party providers on the basis of our legitimate interests and for establishing the contract between you and us in order to integrate their services. This always requires that the third-party providers are aware of certain and mostly technical or anonymised information as without that data they would not be able to provide their services. Your information is therefore necessary for us to provide our services to you. The following provides an overview of third-party providers, together with links to their privacy policies, which contain further information on the processing of data and so-called opt-out measures:

  • Clerk Inc. for authentication and user management;
  • DigitalOcean, LLC for providing the cloud infrastructure on which we run our internal analytics tools;
  • Google LLC Firebase Firestore for game data storage, user uploaded images, real time communication, game updates, players profiles;
  • Google LLC for Google Analytics, to provide website traffic analysis and user behavior insights;
  • Google LLC (Google Maps) to power our optional location-based game features.
  • Hotjar Ltd. for user behavior analytics and feedback;
  • images.weserv.nl (wsrv.nl) for real-time image caching, resizing, and optimization of user-uploaded images;
  • OpenAI OpCo, LLC to provide in game interactions, including the analysis of voice messages for certain riddles;
  • PostHog Inc. for product analytics and market research;
  • Resend (resend.com) for sending transactional emails;
  • Neon.tech as our database provider for storing core application and user data;
  • Vercel Inc. for website hosting and deployment.
  • Sentry (Functional Software, Inc.) technical monitoring and health of the system.

Credit/Debit Cards Payments

Payment by credit card and debit card is made via the payment service provider Stripe to which you pass on your payment details during the checkout, for payment processing. The legal basis for the provision of a payment system is the establishment and implementation of the user contract for the use of the service.

Data Sharing

In certain cases, it is necessary to transmit the processed Personal Data in the course of data processing. In this respect, there are different recipient bodies and categories of recipients.

Internal

If necessary, we transfer your Personal Data within unboxing cycles. Of course, we comply with the associated legal framework and ensure that your data is processed properly. Access to your Personal Data is only granted to authorized employees who need access to the data due to their job, e.g., to provide our services or to contact you in case of queries.

External bodies

Personal Data is transferred to our service providers in the following instances:

  • in the context of fulfilling our contract with you,
  • to use marketing services and to advertise our services online,
  • to communicate with you,
  • to provide our website, and
  • to state authorities and institutions as far as this is required or necessary.

International transfers

We may transfer your Personal Data to other companies as necessary for the purposes described in this Privacy Policy. In order to provide adequate protection for your Personal Data when it is transferred, we have contractual arrangements regarding such transfers. We take all reasonable technical and organizational measures to protect the Personal Data we transfer.

Security of your data

In order to protect the data stored with us in the best possible way against accidental or intentional manipulation, loss, destruction or access by unauthorized persons, we use appropriate technical and organizational security measures. The security levels are continuously reviewed in cooperation with security experts and adapted to new security standards.

Nevertheless, internet-based data transmissions can always have security gaps, so that absolute protection cannot be guaranteed. And databases or data sets that include Personal Data may be breached inadvertently or through wrongful intrusion. Upon becoming aware of a data breach, we will notify all affected individuals whose Personal Data may have been compromised as expeditiously as possible after which the breach was discovered.

Marketing

Insofar as you have given us your separate consent to process your data for marketing and advertising purposes, we are entitled to contact you for these purposes via the communication channels you have given your consent to.

You may give us your consent in a number of ways including by selecting a box on a form where we seek your permission to send you marketing information, or sometimes your consent is implied from your interactions or contractual relationship with us. Where your consent is implied, it is on the basis that you would have a reasonable expectation of receiving a marketing communication based on your interactions or contractual relationship with us.

Direct Marketing generally takes the form of email using the services of Postmark (ActiveCampaign, LLC) or resend.com but may also include other less traditional or emerging channels. These forms of contact will be managed by us, or by our contracted service providers. Every directly addressed marketing sent or made by us or on our behalf will include a means by which you may unsubscribe or opt out.

Social Media

General

We are present on social media on the basis of our legitimate interest. If you contact or connect with us via social media, we and the relevant social media platform are jointly responsible for the processing of your data and enter into a so-called joint controller agreement. The Personal Information collected when contacting us is to handle your request and the bases are both your consent and our legitimate interest.

Market research and advertising

In addition, your data may be processed for market research and advertising purposes. For example, usage profiles can be created from your usage behavior and the resulting interests. This allows, for example, advertisements to be placed within and outside the platforms that presumably correspond to your interests. The legal basis is our legitimate interest.

When you visit our profiles and interact with us and others

When you visit our social media profiles, we, as the operator of the profile, process your actions and interactions with our profile (e.g., the content of your messages, enquiries, posts or comments that you send to us or leave on our profile or when you like or share our posts) as well as your publicly viewable profile data (e.g., your name and profile picture). Which Personal Information from your profile is publicly viewable depends on your profile settings, which you can adjust yourself in the settings of your social media account. The legal basis is our legitimate interest and your consent.

Advertising

We would like to show you interesting advertising outside of our website and use various third-party tools and cookies for this purpose. These collect and process information about your activities on our website - for example, which products you are interested in or which pages you visit. By knowing what you are looking for and how you use our website, we can adapt our advertising to your needs. And thus increase the likelihood that you will also be shown suitable and interesting advertising outside our website.

We also analyze this data to evaluate the relevance of the advertisements and to optimize the advertisements for you. Through the tools, your browser regularly establishes a connection to the server of the tool provider when you visit our website. For some tools, we have no direct influence on what data is processed by the providers. The following personal data may be processed by third-party providers i) HTTP header information (e.g., IP address, web browser, website URL, date and time); ii) measuring pixel-specific data (e.g., pixel ID and cookie ID); and iii) additional information about visits to our website. The legal bases for processing are our legitimate interest and your consent in case of cookies. For further information, please refer to our Cookie Policy.
