How Crumblinks handles data

Crumblinks is a deterministic attribution layer for Steam, Minecraft, and Roblox games. This policy explains what data may be processed when studios, publishers, developers, performance marketing teams, UA teams, growth teams, creator teams, and influencer marketing teams use Crumblinks to measure attribution and conversions.

Last updated: July 7, 2026

1. Scope

This Privacy Policy applies to the Crumblinks website, product dashboard, tracking links, SDKs, server-side event endpoints, and related services. It covers data we process for our own website and account operations, and data we process on behalf of customers who configure Crumblinks for their campaigns, games, websites, or creator programs.

Private application and dashboard data is not intended to be public or crawlable. Public pages such as the marketing website, this policy, sitemap, and documentation files may be accessible without signing in.

2. Roles

For customer-configured attribution and event measurement, the customer decides what campaigns, links, events, platforms, and conversion goals are measured. In that context, Crumblinks generally acts as a service provider or processor for the customer. For our own website, account administration, security, and communications, Crumblinks may act as an independent controller of the relevant data.

3. Data We May Process

Customer account and workspace data

When a customer or user creates an account, accesses a workspace, or contacts us, we may process account and contact data such as name, email address, company or team information, role, login metadata, workspace settings, project names, tracker configuration, and support messages.

Campaign, link, and attribution data

Crumblinks may process campaign and attribution data such as tracking links, landing pages, referrers, UTM parameters, campaign names, source and medium labels, creator or influencer identifiers configured by the customer, ad campaign identifiers, click IDs, timestamps, and Crumblinks tracking IDs.

Crumblinks ID

A Crumblinks ID, sometimes represented as crumblinks_id or another implementation-specific identifier, is a pseudonymous identifier used to connect clicks, links, campaigns, visits, and conversion events. It is designed to support attribution measurement without requiring Crumblinks to know a player's real-world identity.

Device, browser, and network data

Depending on customer configuration and how a user interacts with Crumblinks-enabled links or pages, we may process technical data such as IP address, user agent, browser type, operating system, device characteristics, language, approximate location derived from IP address, screen or viewport information, timestamps, and cookie or local storage identifiers where applicable.

Game and conversion event data

Customers may configure Crumblinks to receive conversion and product events. Depending on the platform and customer implementation, this may include Steam wishlist events and purchases; Minecraft game or server visits, joins, and purchases; Roblox traffic sources, game or experience visits, and in-game purchases; and other custom events selected by the customer.

4. How Data Is Collected

Data may be collected when a person visits our website, opens a Crumblinks tracking link, lands on a customer page that uses Crumblinks, triggers an event through a customer-integrated SDK or server-to-server integration, signs in to the dashboard, or communicates with us.

Crumblinks may use cookies, local storage, pixels, SDK requests, server-side events, postbacks, and similar technologies to receive and associate events. The exact collection method depends on the customer's implementation and the user's browser or platform settings.

5. How We Use Data

We use data to provide, maintain, secure, and improve Crumblinks. Typical uses include:

6. Customer Responsibilities

Customers are responsible for configuring Crumblinks lawfully and for providing any notices, disclosures, choices, or consents required for their own websites, games, stores, communities, and marketing campaigns. Customers should not send Crumblinks sensitive personal information unless they have a valid legal basis and a written agreement with us that permits that processing.

Practical example: if a customer uses Crumblinks to measure a Roblox experience visit or a Minecraft server purchase from a campaign link, the customer is responsible for making sure their own user-facing notices explain that measurement where required.

7. Sharing and Service Providers

We may share data with vendors and service providers that help us host, secure, operate, analyze, support, or improve Crumblinks. These providers are expected to process data only for the services they provide to us or to our customers.

We may also disclose information if required by law, to protect rights and safety, to investigate abuse, or as part of a business transaction such as a merger, acquisition, financing, or sale of assets. We do not sell customer workspace data as a standalone data product.

8. Third-Party Advertising and Analytics Services

The third-party services that we use on our websites or partner websites are listed below:

These services may process identifiers and event data such as campaign IDs, click IDs, referrers, UTM parameters, Crumblinks IDs or other pseudonymous IDs, device and browser information, network information such as IP address, and conversion or product events. The exact data shared depends on the customer's configuration, the advertising platform, the browser or device settings, and the relevant campaign flow.

9. Retention

We retain data for as long as reasonably needed to provide the service, maintain attribution reports, support customers, comply with legal obligations, resolve disputes, enforce agreements, and protect the service. Retention periods may vary depending on the type of data, customer configuration, contract terms, backup schedules, and operational requirements.

10. Security

We use administrative, technical, and organizational measures intended to protect data from unauthorized access, loss, misuse, or alteration. No internet service can guarantee perfect security, so customers should also protect their account credentials, restrict workspace access, rotate integration credentials when needed, and configure events carefully.

11. International Transfers

Crumblinks may process and store data in countries other than the country where a user or customer is located. Where required, we use appropriate contractual, technical, and organizational measures for cross-border processing.

12. Privacy Rights and Choices

Depending on location and applicable law, individuals may have rights to request access, correction, deletion, restriction, portability, or objection to certain processing. If the request relates to a customer's campaign, game, or workspace, we may direct the individual to that customer or work with the customer to respond.

Browser settings may allow users to block or delete cookies and local storage. Some tracking and attribution features may not work as intended if these technologies are disabled.

13. Children's Privacy

Crumblinks is a business service for game companies and marketing teams. It is not directed to children as a standalone consumer product. Customers are responsible for determining whether their own games, experiences, servers, websites, or campaigns require additional notices, parental consent, age gates, or other protections.

14. Changes to This Policy

We may update this policy from time to time. When we make changes, we will update the date above and may provide additional notice where appropriate.

15. Contact

If you have questions about this Privacy Policy or want to make a privacy request, contact us through the Crumblinks website. If your request concerns a specific game, campaign, creator link, Steam title, Minecraft server, or Roblox experience, please include enough context for us to identify the relevant customer or workspace.
