Family
Family calendar with school, training and doctor’s appointments, bin collection and school holidays as subscriptions, everyone with their own mailboxes, children with a simple account.
Email and calendar in one web app – with your own accounts, for home, family and business.
All mailboxes and calendars in one app: simply connect Gmail, GMX, WEB.DE, Outlook, iCloud or your own domain – the wizard detects the settings. Family calendar with the family bonus, shared inboxes for info@ and service@, resource calendars and uttek Connect for businesses. No new address needed, self-hosted, full source code.
Live demo without sign-up · your own demo copy with sample data (family, personal, business) · simulated mailboxes – nothing is sent · admin view-only

Three mailboxes, two calendars and a different app every time: personal at GMX, work at the company, the family calendar on your partner’s phone, club dates as a PDF attachment. And at work everyone reads the info@ inbox, but nobody knows who has already replied.
uttek Mail & Calendar brings everything into one web app – in the browser and as an app on your phone. You keep your addresses: the setup wizard detects Gmail, GMX, WEB.DE, Telekom, Outlook, iCloud, Yahoo, Posteo, mailbox.org, IONOS, STRATO and your web host’s mailboxes and shows where an app password is needed. If you want your own address such as anna@family-example.com, rent web space with mailboxes from a provider of your choice – uttek does not issue addresses and does not store your emails on its own servers.
Calendars from CalDAV and ICS subscriptions appear next to your own, and invitations are accepted straight from the email. With the family package up to six people share a family calendar and an address book; children get their own simple account. Businesses work in the shared inbox with assignment, status and internal notes, book rooms and vehicles in the resource calendar and, via uttek Connect, see jobs from uttek Dispo, shifts from uttek Rota and absences from uttek HR – and turn an email into a ticket with one click.
Starts with SQLite – no database setup. As your business grows, switch to MySQL/MariaDB (PostgreSQL optional) with the admin wizard: test the connection, migrate all data, verify counts, switch over – with rollback.
The upgrade wizard is a uttek standard and is being built into every tool in upcoming versions.
With uttek Connect you link your uttek tools by address and key: tickets become Dispo jobs, customer data comes from the CRM, feedback lands in the ticket and the customer history, shop orders in the CRM – at no extra cost and without a cloud middleman.

No. uttek Mail & Calendar works with your existing addresses at Gmail, GMX, WEB.DE, Outlook, iCloud, your web host or your company. If you want an address with your own name, rent web space with mailboxes from a provider of your choice (usually €1–5 a month) – the wizard shows how. uttek does not issue addresses and does not store your emails on its own servers.
Enter the email address and password – the wizard detects the rest for all major providers and most web hosts. Google, Apple, Yahoo and Telekom require an app password; the wizard links the right page. Calendars can be connected at the same time.
The family package covers up to six people with their own login. Everyone shares a family calendar and a family address book; each person connects their own mailboxes and only sees their own emails. Children get a simple account without account management.
Shared inboxes such as info@ and service@ with assignment, status and internal notes so no enquiry is left behind; team and resource calendars for rooms and vehicles; snippets, filter rules and reports. Via uttek Connect, jobs from uttek Dispo, shifts from uttek Rota and absences from uttek HR appear in the calendar.
Yes, via IMAP and SMTP. Gmail requires an app password (with two-factor sign-in). For some personal and business accounts Microsoft only allows sign-in via its own Microsoft window – the wizard then shows what to do. For GMX, WEB.DE, Telekom, IONOS, STRATO and most web hosts, the normal password is enough.
Web space with PHP 8.2 or newer – often from the same provider that hosts your mailboxes. The database (SQLite) is built in; MySQL/MariaDB is optional from Business Pro. A cron job every five minutes fetches new emails and events even when the app is not open.
Yes, without sign-up. Every visit gets its own demo copy with sample data (family, personal, business), deleted after 24 hours. The mailboxes in the demo are simulated – nothing is sent or fetched; all people and addresses are fictitious.
Passwords are only stored as a secure hash; new passwords need at least 12 characters and are checked offline against a list of leaked passwords. Everyone can set up two-factor sign-in via an authenticator app (e.g. Google Authenticator, Aegis) with backup codes, and the admin can require it per role. After 5 failed attempts a login lockout with increasing delay applies; “forgot password” sends a single-use link valid for 1 hour. Optionally notes on emails and contacts – mailbox and calendar passwords (always encrypted) get a second layer are stored encrypted with AES-256-GCM, with the key outside the web root. The “Security (status)” page shows all measures at a glance.
