Early shift uncovered? Klacks suggests a replacement who fits. It checks rest periods before the plan goes out.
Klacks can be set up with reduced daily target hours for all staff during the holy month of Ramadan, monitors the overtime cap live, optionally with a hard block in automatic planning, and maintains hour accounts whose hours you export for your payroll (Klacks does not generate a WPS file) — installed on your own premises, so your scheduling and staff data required under the PDPL are stored on your own servers.
No license fees under the AGPL.
- Your data stays with you
- AI with free choice of model

This is how you talk to Klacksy — you can see these sentences in the videos:
For small, medium-sized and large businesses
By company size
- Small · up to 50 employees You say what you need — Klacks plans, you confirm. Without license fees, on an office PC.
- Medium · 50 to 250 employees Fewer people, the same number of shifts: Klacks fills gaps in line with your rules and suggests a replacement who fits.
- Large · over 250 employees No license per employee, no user fees, no subscription — with 2,000 people the maths works out differently than with 20.

Monday, 6:40 a.m. Someone is missing from the early shift.
You quickly assign a colleague who worked a late shift until 10 p.m. yesterday. Klacks flags it immediately: rest period too short — 9 hours instead of the configured 11. You see the problem before the schedule goes out, not only when someone works it out afterwards.
Watch in the video: rest period too shortEveryday scheduling in UAE businesses Ramadan, the overtime cap and WPS deadlines
- Shortened Ramadan hours for everyone During the holy month of Ramadan, regular daily working hours are cut by 2 hours — with no reduction in pay, for every private-sector employee regardless of religion (Federal Decree-Law No. 33 of 2021, Art. 17, read with Cabinet Resolution No. 1 of 2022).
- Daily overtime limit & the 144-hour cap Overtime is capped at 2 hours a day, and total working hours may not exceed 144 hours per 3-week period — paid at a minimum +25% premium, rising to at least +50% between 22:00 and 04:00 (Art. 19).
- Meeting WPS payroll deadlines Onshore private-sector wages must be paid electronically through the Wage Protection System (WPS) — employers who miss the 15-day payment window risk a freeze on new work permits (Ministerial Resolution No. 340 of 2026, in force since 1 June 2026).
- Keeping biometric time tracking PDPL-compliant The PDPL (Federal Decree-Law No. 45 of 2021) explicitly classifies biometric data as sensitive personal data — cross-border transfers are tightly regulated.
What Klacks can do — in real recordings
Short videos from the running app, sorted by topic. Choose a chapter; only the video of the open chapter ever plays.
Note on the sample data: All names, places (for example Winterthur), addresses and figures in these recordings are fictitious demo data with a Swiss background, written in Latin script. They only illustrate the product – you do not need to know or be able to read them. In your own installation you enter your own data, and the interface is multilingual.
- Klacksy helps you get it right in every one of these cases: describe your rule in the chat in your own words, for example “Sundays earn a 50% surcharge.” — Klacksy asks follow-up questions, shows a preview and only saves once you confirm.
- Klacksy also creates scenarios and starts planning inside them — tell it in the chat, for example: “Plan Winterthur from November 2 to 8.”
- Klacksy, the built-in AI assistant, can also do all of this for you on request — for example, tell it in the chat: “Add expenses of 24.50 for Mia on October 6.”
A calendar that keeps pace with the moon
In the United Arab Emirates, all official public holidays are decreed centrally by the UAE Cabinet — uniformly for all seven emirates, with no cantonal or municipal variation like in Europe. The real challenge lies elsewhere: holidays whose exact date is only confirmed at short notice, and businesses that plan across several Gulf states.
- Uniform nationwide, confirmed at short noticeEvery holiday applies equally across all emirates — but religious dates such as Eid al-Fitr and Eid al-Adha are confirmed only by a national moon-sighting committee, often just days in advance. New dates can be added to Klacks the moment they're announced.
- Mix calendarsA Dubai business with branches in Saudi Arabia, Qatar or Oman needs several country calendars running at once — moon sightings occasionally differ by a day between Gulf states, and national days fall on different dates to begin with.
- Binding or purely informationalFor each calendar, you decide whether a holiday affects hours & premiums — or simply appears as a reminder.
It all comes down to the settings
Klacks offers countless ways to calculate rules and hour credits for nights, weekends, public holidays and overtime — exactly the way your contracts and company agreements require.
- Nights and weekends You set the night window and the surcharge rates yourself, and choose up to three weekend days — as a multiplier that is added to the hours worked as a time credit in hours.
- Public holidays and overtime A separate public-holiday rate, and overtime per day or per week in up to three tiers. When several surcharges fall on the same hour, the highest one applies — or all of them add up.
- Your own calculation with a macro If that is not enough, a macro does the maths: a short script using weekday, time of day, public holidays and contract values — with conditions, loops and functions of your own.
- Scheduling rules Rest periods, maximum daily and weekly hours, consecutive working days, free Sundays or hour caps per period — each one as a warning or, in automatic planning, as a block.
Rule violations: Klacks warns you instantly
Klacks flags time collisions, rest periods that are too short, too many consecutive working days and work on holidays right as you plan — as an error or warning in the error list.

How Klacks takes the load off UAE businesses
From configured Ramadan target hours to the hour basis for payroll — everything works together.
Ramadan target hours can be set for everyone
Klacks can be set up with daily target hours reduced by 2 hours for all staff during the holy month of Ramadan — with no need to manually adjust every single schedule.
Overtime daily limit & 144-hour cap monitored live
Klacks warns before a shift is assigned if the 2-hour daily limit would be exceeded, and monitors total working hours per 3-week period live against the 144-hour cap; the night-work premium is credited automatically as a time credit, with an exactly configurable time window (22:00 to 04:00).

On request, Klacks hard-blocks such violations in automatic planning (block mode, configurable per rule type); with manual planning it stays at a warning.
Hour export for payroll
Klacks keeps hour accounts reconciled against the schedule and provides the hours as a CSV/XLSX export for your payroll — a WPS file and the payment of wages themselves are outside Klacks, and the deadlines under Ministerial Resolution No. 340 of 2026 remain with your payroll processing.
Data kept on your own servers (PDPL)
Your scheduling and staff data are stored on your own servers — and with a locally hosted AI model, also without cross-border AI requests, whose data transfer the PDPL tightly regulates for sensitive personal data.
Klacksy: rule-based, not a black box
The built-in AI assistant Klacksy understands instructions in everyday language and controls Klacks; the rule-based planning engine calculates the plan — traceable through defined rules, not an opaque AI decision.
Absences covered fast
If someone calls in sick, Klacks immediately shows who is qualified and available — without tearing up the whole schedule.
Test plan changes risk-free
Before a plan change goes live, you can run it through as an isolated copy — the daily overtime limit and the 144-hour cap, together with premiums, are calculated live exactly as in the real plan.
Read more
Only once everything checks out do you apply the variant; until then, your live schedule stays untouched. This lets you prepare a suitable scenario in advance for foreseeable situations — such as a staff member calling in sick or a sudden spike in orders — so you're ready to act immediately when it matters, instead of improvising under time pressure. There's no artificial limit on the number of scenarios — create as many as your planning needs.
Klacksy: the assistant built into your team's workflow
Klacksy isn’t a bolted-on marketing chatbot, but embedded directly in the Klacks interface. Staff and schedulers ask about shift times via chat or check availability. A built-in skills and rules system ensures Klacksy only ever makes traceable suggestions — never a black-box decision. For businesses with strict PDPL requirements around sensitive personal data, the AI model can also be hosted locally.
Note on the sample data: All names, places (for example Winterthur), addresses and figures in these recordings are fictitious demo data with a Swiss background, written in Latin script. They only illustrate the product – you do not need to know or be able to read them. In your own installation you enter your own data, and the interface is multilingual.

Open source under AGPL-3.0
The source code of the backend and the interface is public. Your IT team can check what Klacks does with personnel data — and keep running Klacks independently of us.
-
Data on your servers
Klacks runs on your own servers. Personnel data is held in your infrastructure; the data-protection assessment under the laws of your country remains with you.
-
Your choice of AI model
Klacksy works with the model of your choice — from external providers to a model you run yourself. You decide on cost, data protection and provider.
-
No lock-in with big cloud providers
Your data lives in your own database (PostgreSQL), the code is open, and you switch the AI provider in the settings.
No license fees does not mean no costs. Servers, operation and maintenance cost money, and so does an external AI model — what you do not pay is a fee per employee.
Your data is stored on your own servers. For address lookup and route calculation, Klacks uses public services based on OpenStreetMap by default; addresses and coordinates are sent there without names. The documentation lists which other external services Klacks calls.
Your AI agents work directly with Klacks
Klacks speaks MCP (Model Context Protocol), the open standard through which AI agents work with software. Any agent that speaks the open standard MCP — such as Claude, Cursor or your own agents — can work directly with Klacks: with the tools Klacksy uses as well, and only with the rights of the connected user.
Operating steps in the interface and sensitive functions such as managing access tokens stay locked, and an agent never receives more than supervisor rights.
