Privacy & data handling
Data collected
Before adding any analytics solution to a product, teams need a precise understanding of what data is collected and whether any personal data is processed or could be derived from it.
- What data is collected exactly?
- concrete schema: event payload, metadata, identifiers.
- What specific data points does TelemetryDeck collect?
- Is any personal data processed or derivable?
- IP handling (stored? truncated? discarded?)
- User identifiers (hashed? salted? reversible?)
- Fingerprinting (yes/no)
- Is there any PII (Personally Identifiable Information) collected?
TelemetryDeck's legal setup
Compliance and privacy
Compliance is not a checkbox. It’s about understanding the legal foundation of how data is collected, processed, and stored, and whether that holds up under real scrutiny.
Why is TelemetryDeck GDPR-compliant without consent banners?
At TelemetryDeck, we do not process any personally identifiable information (PII). We ensure this through various measures. These include anonymizing user identifiers, blocking certain personal data points such as email addresses, masking timestamps, collecting location data exclusively at the country level, and other methods.
Since all data protection laws (such as the GDPR and the CCPA) apply to the processing of personal data, and TelemetryDeck processes only non-personal data, our service does not fall within the scope of these data protection laws.
For further information, please read our article about anonymization of user data.
Where does TelemetryDeck store usage data?
We store the usage data exclusively within the European Union. All data is hosted at HETZNER in Nuremberg. Some parts of our infrastructure are hosted at Azure in Amsterdam and AWS in Frankfurt. In 2026, we finalize moving away from Azure and AWS, and our infrastructure will be hosted exclusively at HETZNER soon.
Does TelemetryDeck provide a Data Processing Agreement (DPA)?
Yes, you'll find our DPA here:

Size, dependencies, maintenance status
How long does it take to integrate TelemetryDeck?
For basic tracking (1 event with payload and metadata will be sent at every app opening), we estimate 4 minutes from account creation to first test data. With this setup you will see usage and device data in all our pre-built dashboards.
We recommend setting up advanced tracking when you have specific questions such as feature usage, onboarding funnel, or conversion rates of paywall screens.
How long?
- Data ingestion pipeline
- How data flows (client → API → storage)
- Reliability guarantees (retries, batching, offline support)
- Performance impact
- SDK overhead (CPU, memory, network usage)
- What is the overhead (CPU, memory, bandwidth) when integrating TelemetryDeck?
- Are there benchmarks or customer case studies?
- Failure modes
- What happens if TelemetryDeck is down?
- Does it block the app? (this better be a hard “no”)
What hosting options does TelemetryDeck provide?
Since we started with our public beta in 2021, we have been hosting TelemetryDeck, its customers, and data in the cloud. We currently don’t offer on-premise hosting or self-hosted solutions. Please visit this page for more information regarding hosting.

Product Capabilities
Although our customers have many things in common, every use case is unique. We can help you determine whether TelemetryDeck can address the challenges your organization faces using anonymized usage analytics.
What are TelemetryDeck's core use cases?
Most of our customers need reliable device data, such as device model and operating system version number. Understanding the technical setup of your users helps with roadmap and version support decisions. Besides that, our most popular features are
- Funnel analytics (understanding drop-offs)
- Acquisition analytics (understanding user growth)
- Activation analytics (understanding the time-to-value)
- Retention tracking (understanding the stickability of your product)
Does TelemetryDeck provide cross-platform tracking?
Yes, TelemetryDeck can identify a returning user across an app and a web app from the same TelemetryDeck account. This is only possible with registered app users.
Tracking users over different external platforms is not possible with TelemetryDeck's privacy-first approach. We do not hand over user identifiers at any point.
What other questions can be answered with TelemetryDeck's data?
You can directly query the database. We help you build powerful charts with a preset of filters and a powerful TQL. We also support using your AI agent to build queries for you and will release an MCP in the near future.
Do we need a data scientist or engineer to use TelemetryDeck?
TelemetryDeck provides a broad set of pre-built dashboards that answer a good portion of typical product analytics questions. Your usage data will be interpreted within these charts automatically. For more advanced tracking, you need a developer to set up custom events within your product.
While we are a big fan of data scientists in general, we are passionately building a tool that people without expert knowledge can use.
Data Ownership & Portability
- Who owns the data?
- Who owns the collected data?
Can we export the data from TelemetryDeck to our own systems?
TelemetryDeck provides a data export function. You can export the whole database or selected data from one chart.
For our enterprise customers, we provide custom setup.
Does TelemetryDeck have a vendor lock-in?
No. It is always possible to move away from TelemetryDeck. We provide an export function for all the collected data. All you do to leave TelemetryDeck is to remove the SDK from your product and make sure all your users get an update.
Can we demand a data deletion?
Yes, we can provide a one-time or an automatic deletion (e.g., after a certain time period). Please contact us to discuss the option that fits your internal compliance and data regulation.
Security
How does TelemetryDeck manage authentication & access control?
To log in to the TelemetryDeck dashboard, you can use any of these options:
- Username + password
- GitHub
- Okta (for our enterprise customers, on request)
We also support role-based permissions.
How does TelemetryDeck manage data isolation?
We provide a multi-tenant architecture. Every customer of TelemetryDeck gets their own Namespace. Please visit our blog post to learn more about Namespaces.
How does TelemetryDeck secure transmitted and stored data?
- Encryption
- Authentication
Does TelemetryDeck provide TOMs?
Yes, we can provide a list of our technical and organizational measures for data protection at request.
Calculation cost
Straightforward pricing that doesn't break the bank
We made it our mission to support makers from all over the world in making good products even better. In our opinion, this is only possible if TelemetryDeck offers its service at fair conditions.
What is TelemetryDeck's pricing model?
TelemetryDeck has a usage-based pricing model. The more data your products are sending to our servers, the higher the monthly cost.
For our self-service customers, we provide a pricing table where they can calculate monthly and annual payments depending on volume. We also provide a sample calculation. Please visit our pricing page.
For our enterprise customers, we provide custom pricing that reflects special needs such as SSO setup, compliance work, team training, and a custom infrastructure. We are happy to discuss options with you. Please visit our contact page.
How does TelemetryDeck's pricing scale?
A lot of our customers (luckily) grow out of their TelemetryDeck plan. We'll let all administrators in your account know in advance if our calculations indicate that you will reach your monthly limit so that you can upgrade on time.
Are there any hidden costs?
No, there are no hidden costs with TelemetryDeck. We do not charge extra for API access, data export, or data retention. However, we will put some features behind a paywall in the future. All existing customers will be grandfathered within the old pricing and feature structure.
Operational fit
Which roles in my team will work with TelemetryDeck regularly?
TelemetryDeck is designed to answer all questions regarding product and usage.
That means your product owner will probably check feature usage. Your marketing team will have an eye on paywall conversion rates. And your engineering people can check device data to decide which OS versions your product should support.
With our notebooks feature, you can build powerful reports for the management team.
How long does it take my team to get value out of TelemetryDeck?
Our setup only takes a blink of an eye. You get your first test data within 4 minutes. However, with app analytics, we rely on Apple and Google to review a new app version. You have to wait until the new version that contains the TelemetryDeck SDK reaches your users. Once that is done, you get real-time data.
Supporting data-based decisions
