In Vinnytsia, you can take the test at the office of a fellow polygraph examiner whom I will recommend; on-site visits in the city and the region are also possible. Based on your situation, I will help you choose a method. Confidential. Official. Professional.
When to take a lie detector test in Vinnytsia
People turn to a polygraph examiner in situations where what matters is the truth, not guesswork.
Infidelity tests and family matters
Suspicions of marital infidelity, hidden relationships, financial and domestic conflicts. An infidelity test helps either to confirm your partner’s fidelity or to end painful uncertainty so that you can move on.
Pre-employment screening
Screening of candidates for positions of responsibility: accountants, drivers, managers, security guards, nannies, domestic staff.
The test can reveal:
- hidden debts and addictions;
- thefts at previous places of work;
- conflicts of interest.
Internal investigations
Theft, fraud, leaks of commercial information, abuse of office. A polygraph helps to quickly narrow down the circle of suspects and to make decisions based on facts.
Protecting your good name
If someone is being accused without grounds, a lie detector test can confirm that they are telling the truth and clear them of suspicion.
EyeDetect for clients from Vinnytsia — an eye-based lie detector
Besides the classic polygraph, there is the modern EyeDetect (Eye Detect) technology — a contactless method of verifying truthfulness. The test is taken at the station in Lviv; its online counterpart on a smartphone is VerifEye.
EyeDetect analyses:
- micro-movements of the eyes;
- pupil responses;
- the level of cognitive load.
Advantages of EyeDetect
- ✅ No sensors on the body — minimal stress;
- ✅ Speed — the test takes up to 45 minutes, result included;
- ✅ Accuracy of 86–90%;
- ✅ The result cannot be “bought” — the conclusion is produced by an algorithm, not a person.
EyeDetect is often chosen by people who worry about the human factor or possible manipulation of the results.
The technology can be used:
- as an alternative to the classic polygraph;
- as an additional check;
- remotely — in the VerifEye format on a smartphone.

Frequently asked questions (FAQ)
Can a polygraph be fooled?
Practically no. Countermeasures — controlled breathing, muscle tension, sedatives — usually show up on the charts and the motion sensor, and the examiner notes them in the conclusion. EyeDetect tracks the pupils and eye movements, which a person does not consciously control.
Is a polygraph test legal?
Yes, provided the person gives voluntary written consent.
Does nervousness show?
Yes, but nervousness does not equal lying, and it is taken into account when the results are analysed.
Are there any contraindications?
Certain medical conditions are discussed individually before the test begins.

How a polygraph test in Vinnytsia works — step by step
Vinnytsia is about 360 km from Lviv, so Andriy Maryniak does not conduct tests here in person: for Vinnytsia we will recommend a fellow polygraph examiner, and with no travel there is the online VerifEye test.
- Your enquiry and an assessment of the request. You describe the situation, and together we decide whether it can be tested instrumentally. A polygraph works with specific facts: did the person take it, did they know, were they involved.
- Choosing the topics. Ideally 1–3 topics per test. This is not a limitation of the method but a condition of accuracy: the more unrelated topics there are, the less reliable the result on each one.
- Voluntary written consent. Signed before the start. No test is carried out without consent.
- Pre-test interview. From 40 minutes. We discuss how you feel, any medication and chronic illnesses; every test question is read out in advance.
- Testing and conclusion. 40–90 minutes of recording reactions, followed by analysis and discussion. You get a verbal result straight after the test and the written conclusion on the day of the test — in complex cases within 24 hours.
Typical requests in the Vinnytsia region
Agribusiness and processing
The Vinnytsia region is one of the largest agricultural regions in the country, and this shows in the pattern of corporate orders. Typical topics: shortages of grain and raw materials, discrepancies in weights at intake, fuel siphoned from machinery during sowing and harvest, side deals when buying from small farms.
Food production and warehouses
Checks on financially accountable staff, investigations into shortages of finished products, and screening of candidates for positions with access to warehouses and cold storage.
Trade secrets and key employees
Manufacturing and pharmaceutical companies and IT firms come to us when they suspect a leak of formulas, client databases, contract terms or tender information. Testing is often carried out preventively — for a small circle of people with access.
Family and private requests
Infidelity tests, suspicions of debts, gambling or addictions, screening of domestic staff and nannies. Only with the person’s voluntary consent.
Vinnytsia and the towns of the region
Clients come from all over Vinnytsia — the Staromiskyi district, Zamostia, Vyshenka, Tiazhyliv, Piatnychany, Akademichnyi — and from other towns of the region: Khmilnyk, Zhmerynka, Koziatyn, Mohyliv-Podilskyi, Haisyn, Ladyzhyn, Bar, Tulchyn, Nemyriv, Kalynivka and Pohrebyshche.

FAQ — lie detector test in Vinnytsia
How much does a test in Vinnytsia cost?
The online VerifEye test — from 2,500 UAH (≈ €50); StimulTest — from 900 UAH (≈ €18) per question. In Lviv a classic polygraph test for private clients costs 3,000–8,000 UAH (≈ €59–160), an internal investigation for business — 3,000–8,000 UAH (≈ €59–160) per person, EyeDetect — from 5,500 UAH (≈ €110), a forensic psychophysiological examination — from 20,000 UAH (≈ €395). The price charged by a fellow polygraph examiner in Vinnytsia may differ — we will give you an idea during the consultation.
Does it make sense to book a test for just one person?
Yes. If one person needs to be tested quickly, the simplest option is the online VerifEye test on a smartphone. For a classic polygraph test, we will recommend a fellow polygraph examiner in Vinnytsia or arrange a test in Lviv.
How many employees can be tested in a day?
With a classic polygraph, three or four people per full working day. If more people are involved in the investigation, the testing is planned over several days, or the circle is first narrowed with the online VerifEye test taken on a smartphone.
Can seasonal workers be tested?
Yes, the procedure is the same: voluntary written consent, the pre-test interview, the test. For seasonal crews, a shorter screening format with a narrower list of topics is most often used.
What if an employee refuses?
Refusing is their legal right. It is not proof of guilt, cannot be recorded as a negative result and is not grounds for dismissal or disciplinary action. It is worth telling the team this in advance — it eases tension and increases the share of people who agree voluntarily.
Can a candidate be tested before being hired?
Yes, this is standard screening practice: the test covers the experience the candidate claims, the reasons for leaving previous jobs, any conflict of interest and any facts the candidate is hiding. Again, only with consent.
Does your state of health affect whether you can take the test?
Certain conditions and medications are discussed before the start — that is exactly why the pre-test interview is mandatory. If the test cannot be conducted properly, it is postponed.
How confidential are the results?
The conclusion is given only to the client who ordered the test. The data are not published, not passed on to third parties and not used for any other purpose.
