Last updated 21.09.2026. The table below lists every kind of data we store about you and your family, why we keep it and for how long.
| Category | What is stored | Why | Kept for |
|---|---|---|---|
| Your organiser account | Name, email address, hashed password, last sign-in time | To let you sign in to the console and to know it is you | Until you close the account |
| Your family | Family name, billing email address, the country you live in | To hold the family pool, to answer questions about payments, and to check we are allowed to serve your country | Until you close the account |
| Family members | The name you give, an email address only if you choose to add one, their spending limit, the countries they can use | To get a SIM for them and to hold to the limits and countries you set | Until you remove the member or close the account |
| SIMs | Plan, country, ICCID, activation code, the connectivity provider's order reference | To show you the SIM so it can be installed, and to return the money to the pool if the provider fails | Until you close the account |
| Family pool movements | Each movement in or out, its amount, its reason and the balance after it | So you can see where your credit went, and so a refund can be checked | Until you close the account |
| Payments | Amount, outcome, the card processor's reference, whether it was a test transaction | To add credit to the pool and to answer a question about a payment | Until you close the account |
| Messages you send us | Name, email address, subject, message, and the family member you name if you name one | To answer you | Up to two years |
| Password reset requests | The email address and a hashed, single-use token that expires | To let you set a new password without us ever knowing the old one | Until used or expired |
PERDIEM is a service for families, bought by individuals or by a business on their behalf. The organiser is the adult who opens the account and enters the details of each family member, who may include children. We never contact family members, and we hold nothing about them beyond what the organiser enters.
You enter them in the console. They pass once through our server to the card processor to take that single payment. We never store or log them. We keep the amount, the outcome and the processor's reference.
Four kinds of service provider process data on our instructions: a hosting provider, a database provider, a card processor and a connectivity provider. The connectivity provider receives the plan and an order reference, not your family members' names. We sell nothing to anyone.
Four things are stored in your browser, none of them used to track you: the sign-in cookie, the currency you pick with the EUR / USD switch, the record of your cookie choice, and a note that the opening animation has played. The cookie policy lists all four. Nothing on this site reports your visits to anyone else.
The database and the application are hosted in the European Union. The card processor and the connectivity provider receive only what they need for a payment or a SIM, as described above.
You can download a copy of everything we hold about your family from console Settings, at any time and without asking us. You can also ask us to correct it, or ask us to delete it: closing your account in the console deletes it immediately and permanently. For anything else, write to privacy@perdiem.tech. If you are not satisfied with our answer, you can complain to the Estonian Data Protection Inspectorate (Andmekaitse Inspektsioon), www.aki.ee, or to the data protection authority of the country you live in.
