 > [!WARNING]\
-> We use caching to decrease the load on our servers (see <https://github.com/anuraghazra/github-readme-stats/issues/1471#issuecomment-1271551425>). Our cards have a default cache of 4 hours (14400 seconds). Also, note that the cache is clamped to a minimum of 4 hours and a maximum of 24 hours.

If you want the data on your statistics card to be updated more often you can [deploy your own instance](#deploy-on-your-own) and set [environment variable](#disable-rate-limit-protections) `CACHE_SECONDS` to a value of your choosing.
