Unlike many of our competitors in the analytics world that limit how you can capture and store your data, with Matomo On-Premise or Matomo for WordPress the main limits for you will be your server capabilities and 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.
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?
