Terms of Use and Licence Agreement

Last updated: 30 October 2026

1. Parties

These terms are between İLİKSOFT YAZILIM SANAYİ TİCARET A.Ş. ("İLİKSOFT") and the person or organisation that uses İLİKSOFT's software, websites, mobile applications and devices (the "Customer").

Downloading, installing, activating, purchasing or using a product means accepting these terms. A person who accepts on behalf of an organisation declares that they are authorised to bind that organisation.

2. Scope

These terms apply to all of the following products and services:

They also apply to the iliksoft.com, optiformula.com, yemyap.com, optitmr.com, herdoncloud.com and rumimon.com websites and to our applications on the App Store and Google Play. If a separate written contract has been signed with the Customer, that contract prevails on any conflicting points.

3. Licence

3.1. İLİKSOFT grants the Customer who pays the fee a non-transferable, non-exclusive right to use the software for the work of their own business during the licence period. The software is licensed, not sold; all intellectual property rights remain with İLİKSOFT.

3.2. A desktop licence is valid for 1 year and is used on 1 computer. The licence is activated online by entering the key provided by İLİKSOFT into the software. The software regularly checks the validity of the licence over the internet.

3.3. When changing computers, the Customer contacts the support team. The licence on the old computer is closed and activated on the new one.

3.4. If the licence is not renewed when its term ends, it is closed and the software cannot be used. Files saved on the Customer's computer are not deleted.

3.5. When an expired licence is renewed, the new period starts from the old end date, not from the renewal date, and lasts 1 year:

3.6. The Customer may not:

• Copy, rent or offer the software for sale, let third parties use it, or use the licence on more than one computer
• Reverse engineer the software, try to access its source code, or modify it (except where permitted by the Law on Intellectual and Artistic Works (Fikir ve Sanat Eserleri Kanunu, FSEK))
• Bypass or disable the licence check
• Try to access the services without authorisation, overload them or defeat their security
• Export the nutrient databases in the software in bulk and use them in another product

4. Cloud services and subscription

4.1. The cloud services of YemYap, HerdOnCloud and Rumimon are provided on an annual subscription. The subscription starts on the day payment is received and lasts 1 year.

4.2. New customers can use a 7-day free trial. If no subscription is purchased at the end of the trial, the account is closed and the data entered during the trial is deleted after 90 days.

4.3. If the subscription is not renewed, access to the service is closed. The Customer may request an export of their data within 90 days after the subscription ends. The data is permanently deleted 6 months after the end of the subscription.

4.4. The Customer is responsible for keeping the usernames and passwords of their account confidential and for all actions carried out through their account. On noticing unauthorised access, the Customer immediately reports it to info@iliksoft.com.

4.5. İLİKSOFT makes reasonable efforts to provide the services without interruption. Planned maintenance is announced in advance wherever possible. İLİKSOFT is not responsible for interruptions caused by the internet infrastructure, the hosting provider or force majeure.

5. Rumimon devices

5.1. Rumimon collars are sold to the Customer; ownership of the device passes to the Customer on delivery. The device's software (firmware) is used under licence.

5.2. For commercial buyers the warranty period is 6 months from delivery. For buyers who are consumers, the 2-year statutory period in Law No. 6502 on Consumer Protection (6502 sayılı Tüketicinin Korunması Hakkında Kanun) applies.

5.3. The warranty does not cover faults caused by impact, crushing, incorrect fitting, opening or repair by anyone other than İLİKSOFT, or use contrary to the user manual.

5.4. Device data is viewed through the cloud subscription. Without a subscription the device may collect data, but the data cannot be viewed in the application.

6. Fees and payment

6.1. Prices are stated in the offer, the invoice or on the sales page and, unless stated otherwise, exclude VAT.

6.2. Payment can be made by credit card, debit card or bank transfer. Card payments are taken through a licensed payment institution; card details are not stored by İLİKSOFT.

6.4. İLİKSOFT may change its prices for new periods. A change does not affect a licence or subscription still in its term.

7. Support and updates

7.1. A Customer with a valid licence or subscription receives support and updates at no additional charge.

7.2. Support is provided on weekdays during working hours by phone, email and remote connection. On-site installation and training are charged separately.

7.3. İLİKSOFT supports only the latest version of the software. Users of older versions may be asked to update for security and compatibility.

7.4. Updates may add, change or remove features. If a core function of a product is removed, İLİKSOFT announces this at least 30 days in advance.

8. Use of results and liability

8.1. İLİKSOFT software consists of calculation and decision-support tools. It does not replace decisions on animal feeding, rations, feed formulas and herd management. These decisions are made by the Customer and the Customer's specialists (veterinarian, animal scientist, feed engineer).

8.2. Results are based on the data the Customer enters. The accuracy and consistency of raw material analyses, prices, nutrient values, animal information and other inputs are the Customer's responsibility.

8.3. Each animal's metabolism, health and environmental conditions are different. For this reason, the yield, growth, milk, health or cost results predicted in TMR, ration and formula calculations may not be achieved in practice. The Customer acknowledges this and agrees not to claim compensation from İLİKSOFT because expected results were not achieved.

8.4. The Customer must check every formula and ration produced by the software before applying it. Rumimon alerts do not replace a veterinary examination.

8.5. İLİKSOFT is not liable for indirect damages such as loss of profit, production, animals, data or reputation. The Customer must back up their data regularly.

8.6. In all cases, İLİKSOFT's total liability is limited to the amount the Customer paid for the product concerned in the 12 months before the event causing the damage.

8.7. The limitations in this article do not apply in cases of intent or gross negligence or where liability cannot be limited by law. The statutory rights of consumers are reserved.

9. Intellectual property and data

9.1. The software, databases, documents, logos and website content belong to İLİKSOFT and are protected by Law No. 5846 on Intellectual and Artistic Works (5846 sayılı Fikir ve Sanat Eserleri Kanunu).

9.2. The data and formulations entered by the Customer and the data collected by Rumimon devices belong to the Customer. İLİKSOFT uses this data only to provide the service, give support and produce statistics that cannot be linked to a person. The processing of personal data is subject to the Privacy Policy.

9.3. İLİKSOFT may use suggestions and feedback sent by the Customer to improve its products without payment.

10. Suspension and termination

10.1. If the Customer seriously breaches these terms (for example by copying the licence or letting third parties use it), İLİKSOFT may close the licence or subscription immediately by notice. In this case the fee paid is not refunded.

10.2. The Customer may choose not to renew their subscription at any time. Stopping use before the term ends does not entitle the Customer to a refund of the fee paid.

11. Force majeure

In events beyond the parties' control, such as earthquake, flood, fire, war, epidemic, general internet or power outage, cyber attack and decisions of official authorities, the parties' obligations are suspended for as long as the event continues.

12. Changes

İLİKSOFT may update these terms. Significant changes are announced on the website and by email at least 30 days before they take effect. For licences or subscriptions still in their term, the new terms apply from the next renewal.

13. Governing law and jurisdiction

13.1. Turkish law applies to these terms, even if the Customer is abroad.

13.2. The Courts and Enforcement Offices of Ankara have jurisdiction over disputes. Consumers may apply to Consumer Arbitration Committees (Tüketici Hakem Heyetleri) within the monetary limits set by law, and to Consumer Courts (Tüketici Mahkemeleri) above those limits.
