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.

- Your operational rules — set up in a chat with Klacksy, automatically checked by the planning engine, no coding required.
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 shortDay-to-day scheduling in Saudi businesses Saudi Labor Law, Ramadan and the 12-Hour Limit
- Standard Hours & the 6-Day Limit Standard working time is capped at 8 hours per day or 48 hours per week (Art. 98). Since the 2025 reform, an additional rule applies: no more than 6 consecutive working days without a full rest day.
- Ramadan: Shorter Working Hours For Muslim staff, actual working hours mandatorily drop during شهر رمضان (Shahr Ramadan) to a maximum of 6 hours per day or 36 hours per week — recalculated every year for exactly this group.
- 12-Hour Presence Limit (Art. 101) No employee may remain at the workplace (التواجد في مكان العمل) for more than 12 hours — including breaks, prayer and meal times. In addition, after a maximum of 5 hours of continuous work, a break of at least 30 minutes is mandatory.
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 follows the moon
In Saudi Arabia, the Ministry of Human Resources and Social Development decrees all four official public holidays centrally — uniformly across the whole Kingdom, with no provincial or municipal level like in Europe. The real challenge lies elsewhere: the two religious holidays, whose exact date is only confirmed at short notice by moon sighting.
- Uniform nationwide, no regional levelEid al-Fitr, Eid al-Adha, National Day on September 23 and Founding Day on February 22 apply unchanged across the whole Kingdom — for the public and private sector alike, with no cantonal or municipal exceptions.
- Mix calendarsA business based in Riyadh or Dhahran with partners in the Emirates, Qatar, Bahrain or Oman needs several country calendars running at once — moon sightings occasionally differ by a day between Gulf states, as they did between Saudi Arabia and Oman in 2023.
- 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 Businesses in Saudi Arabia
From automatic 12-hour monitoring to your own infrastructure — it all fits together.
Standard Hours & 6-Day Limit Monitored
Klacks knows the 8h/48h limit (Art. 98) and the new rule of max. 6 consecutive working days without a rest day — Klacks monitors both limits live and warns in time before either is exceeded.
Read more
On request, Klacks hard-blocks the excess in automatic planning; with manual planning it stays at a warning.
Ramadan Hours Configurable as a Rule
For Muslim staff, the reduced 6h/36h limit (Art. 98) for Ramadan can be configured as a separate rule — Klacks checks the schedule against it and warns when it is exceeded.
12-Hour Limit Monitored Live (Art. 101)
Klacks checks the configured 12-hour daily limit live and warns immediately if a person would be scheduled for longer on a single day.
Read more
On request, Klacks hard-blocks such violations in automatic planning (block mode, configurable per rule type); with manual planning it stays at a warning.
Overtime Premium under Art. 107 as Time Credit
The statutory premium of 50% on the base wage (effectively 150%) can be stored as a time premium; Klacks credits the premium hours, and your payroll system calculates the money amount — since the 2025 reform, optionally also as paid time off in lieu.
Nitaqat Saudization Stays in Your Payroll System
Klacks does not map Nitaqat classification and does not calculate salaries — whether the GOSI salary threshold for the full quota unit (1.0 from SAR 4,000, 0.5 for SAR 3,000 to 3,999) is met is checked by your payroll system.

Installed on Your Premises: Data Storage on Your Servers in Saudi Arabia
Klacks runs on your own infrastructure, and you choose the AI model.

Sensitive personnel and scheduling data (البيانات الشخصية الحساسة) is stored physically on your servers within KSA — with a locally hosted AI model, no AI request goes to an external AI provider; transfers are governed by the PDPL and SDAIA, and the legal assessment remains with you.
Klacksy: Rule-Based, No 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.
Test Plan Changes Risk-Free
Before a plan change goes live, you can run it through as an isolated copy — the 12-hour daily limit (Art. 101) and premiums are calculated live exactly as in the real plan.

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 Built-In Assistant for Your Team
Klacksy isn’t a bolted-on marketing chatbot — it’s 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 makes transparent suggestions — never a black-box decision. For businesses with strict requirements for meeting PDPL/SDAIA, the AI model can also be hosted locally in Saudi Arabia.
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.

In Practice: Ramadan Shifts and the 12-Hour Limit, at a Glance
Klacks checks against the configured rules whether a shift during Ramadan would exceed the reduced 6h/36h limit, or whether an employee would be scheduled for more than 12 hours on a single day (Art. 101) — and warns before the plan is saved.
