  1. How does Alkateia's private chat work? Alkateia is a Brazilian app with text and voice messages, individual conversations, and a family group. It has no followers, public profiles, public people search, or open groups. The aim is to stay in touch with authorized participants without turning family life into public content.
  2. How do parents, children, and grandparents join the same space? An authorized member sends an invitation through a QR code, code, or unique link. It expires in 10 minutes. The person accepts, and the parent, guardian, or administrator approves their entry. This two-step process helps verify who is being added. Minors should use the app with their parents' or guardians' involvement, considering their age and circumstances.
  3. What is included besides messaging? The app offers current location, 15-minute sharing, and live location until canceled. SOS sends a family alert with live location and shortcuts to call the police and fire department. There is also a hidden Snake game as an Easter egg. The chat does not support ordinary photo sharing; photos can be used for profiles and the family.
  4. Does the app provide parental controls for the entire phone? The purpose described here is family communication. It does not promise to read conversations in other apps, block all phone activity, or track someone secretly. To review data and permissions, read the Privacy Policy. Protection also depends on keeping accounts secure and how members use information. (CERT.br)
  5. How many people does one subscription cover? Up to five members in total, including the subscriber. That does not mean five guests in addition to the account holder. The limit is the same for monthly and annual plans. There are no separate charges for each person: one subscription covers the family within that limit.
  6. Who is this model for? Parents and guardians who want a private channel with their children and other authorized relatives, including grandparents and people living far away. The decision depends on everyone being able to use the app and whether its features meet their needs. If you want an open network to meet new people, Alkateia has a different purpose.
  7. How do you choose and subscribe? Compare the plans and terms, explore the app screens and ask questions through support. Subscriptions are purchased in the app, according to the offer displayed. To learn more about safety while traveling, see location sharing and SOS for families.

A family communication app brings together conversations and messages between people who are already part of each other's lives. When choosing one, consider who can join, how members send messages, and whether pricing is per person or per group.
