FAQ
What people ask us most
Do I need internet?
Only to sign in the first time. You don't need it to sell, record expenses or collect credit. Connect now and then so your data gets backed up.
What if I change or lose my phone?
Sign in with your email and the code we send you, and your backed-up data comes back. Anything not backed up before losing the phone cannot be recovered.
Can I use it on my computer?
Yes. Go to libreta.histratos.net/app with the same email. Each computer counts as one device on your plan.
How many devices can I connect?
One on the Free plan. Up to 3 on Premium (phones, tablets or computers).
Is my data safe?
It lives on your phone and is backed up, encrypted, on HI STRATOS servers. We don't sell your information or show ads. See the privacy policy (in Spanish).
How does e-invoicing work?
For now, only in the Dominican Republic. Turn it on in the app and each sale can carry its e-CF. You get 5 a month, 100% free; with Premium (US$3.99 a month) they are unlimited.
How do I cancel Premium?
For now, Premium is turned on and off by messaging us on WhatsApp. Going back to Free deletes nothing.
Is the app in English?
Not yet: the app is in Spanish for now. More languages are coming soon.
