Questions people ask before signing up
Do I still need my analytics tool? Do I have to install a script on my site? How ErdiKnows works, where the data lives, and what it does not do.
Do I need anything else?
Do I still need my analytics tool?
Yes. Erdi is not an analytics tool. Keep the one you have — Erdi is the layer on top.
Do I have to install a script on my site?
No. Erdi never puts a snippet on your pages. Events and numbers arrive through webhooks, pull connectors, or a POST to the API.
What if I use Django, Rails or Go?
You post deploys and daily numbers to one HTTP endpoint. There is no adapter to wait for. The request shape is documented at /docs/api.
Does it work for mobile apps?
Yes. App Store Connect and Play Console pull downloads and installs. RevenueCat posts purchases and cancellations onto the timeline.
What does it actually tell me?
Does Erdi tell me why my numbers dropped?
No. At indie data volumes the noise is usually louder than the signal. Erdi shows the markers and the window. The judgement stays yours.
What happens when nothing shipped?
That is often the useful answer. If the fortnight before a dip is empty, you stop suspecting your own code and look outward.
How fast do events show up?
Webhooks land in seconds. App Store Connect and Play Console report one to two days late; Erdi marks the gap instead of drawing a zero.
My data
Where is it hosted?
In the EU, in Frankfurt. The database and authentication run on Supabase there.
Do you train models on my data?
No. We do not use your events, metrics or mail to train AI systems.
How long do you keep my data?
As long as the account exists. After you delete it, backups roll off within 30 days.
Can I get my data out?
Yes. Settings → Your data downloads a copy of the account. Project overviews also export a CSV of the chart.
Is any of this public?
No. Everything in ErdiKnows is private to your account.
Do you have a DPA?
Yes. The data processing agreement under Art. 28 GDPR is published at /dpa.
Practical
Is there a free plan?
It is free right now, during early access.
What happens if a webhook fails?
The provider retries. A bad signature gets a 401, an unknown or disabled endpoint a 404. Erdi keeps no queue of its own.
Do you support teams?
Not yet. Erdi is built for one person watching their own products. A shared login would muddy who last looked.
What Erdi puts on the timeline is listed on Features. How to send data is in the docs.
