Data Limits – No Limits

Unlike many of our competitors in the analytics world that limit how you can capture and store your data, Matomo does not believe in these limits. The only limit for you will be your server/hard disk space.

No Data Sampling

Matomo does not use data sampling on any analytics report. You always get to view the whole of your data and not a sampled data set.

Table Truncation

For performance reasons, Matomo will by default only archive the first 1,000 rows. You can easily edit the config file to enjoy non truncated reports and see 100% of your data. To do so read How can I force Matomo to not limit the data?

Custom Dimensions

Data Storage and Data Collection Limits

There is no limit. You did not read this wrong. You can keep all your data forever.

By default, all historical visitor data, and all reports are kept. You can choose to anonymize the data or purge the old log or report data after a few months. It’s your decision as it is your data.

Also, we have added a new feature to make data storage management easier, by allowing you to easily delete older logs and reports. This is especially useful if you are using Shared Hosting, or have limited Database space.
