How billing works
- Billing is in advance, once a month, in US dollars.
- The charge is exactly the published price: 5 USD for Standard and 50 USD for Advanced. No surprise fees.
- The reference in Mexican pesos (100 and 1,000 MXN) is informational, so you know roughly how much it is.
- Payment is made by card on Stripe's secure gateway. Your card details never pass through our servers.
- Every charge generates a receipt by email and stays available in your account.
Subscribing for the first time
- You create your account with email and password.
- You choose a plan and pay.
- Your workspace is prepared once (60 to 90 seconds) and you go in to work.
If you already have an account but still need to pay, you can do it from your account or from the plans page.
Changing plans
You can upgrade to Advanced (or downgrade to Standard) whenever you want from your account. The change is reflected in your next charge andnothing of your work is lost: conversations, projects and files stay where they were.
Cancelling
- You cancel from your account, online, with no calls or retention hoops.
- You keep access until the end of the paid period; no further charge is made.
- If you want to come back later, you have 30 days of grace before your data is purged.
- If you delete your account, the purge is immediate and there is no going back.
Refunds
On your first purchase you have 7 calendar days to request a full refund. Write to us at soporte@echidnai.com from your account's email and we process it through the same payment method; it usually shows up in 5 to 10 business days depending on your bank. The detail is in Refunds and cancellation.
If a payment fails
We notify you by email and you have days of grace to update your card without losing your work. The update is done in Stripe's secure portal, reached from your account.
Companies and universities
For teams, classrooms and volume contracts there are custom plans with formal invoicing. Write to us from Contact and we will put it together with you.
