Data controller / Service provider: HNK Tech
Application: Çiftçi AI (com.ciftciai.app)
Effective date: 14.08.2026 · Version: 1.0
Some features in Çiftçi AI are powered by artificial intelligence (AI). This
document explains:
> The short version: AI output in this application is **for information
> purposes only. It does not replace** the advice of an agricultural
> engineer, a veterinarian, the Ministry of Agriculture and Forestry, or your
> provincial/district agriculture directorate. For pesticide dosage, quarantine
> periods and pre-harvest waiting periods, **always follow the product label and
> official sources.**
| Feature | What the AI does | How reliable it is |
| AI Advisor chat | Produces free-text answers to farming questions | General knowledge only; it does not see your field or know your soil |
| Plant disease detection | Examines an uploaded photo and suggests a possible disease, severity and treatment | Not a definitive diagnosis — based on visual similarity |
| Satellite index interpretation | Translates satellite-derived numbers (NDVI etc.) into plain language | The numbers are measurements; the interpretation is an AI estimate |
| Irrigation advice | Suggests an irrigation plan from the weather forecast and field data | Depends on the forecast; if the forecast changes, the plan is wrong |
| Content moderation | Automatically screens community posts and listings | May block wrongly or miss violating content |
No other feature in the application uses AI. Weather data, fire alerts, the
satellite index calculation itself, laboratory results, timesheet records and
marketplace listings are not AI-generated — they are measurements, calculations
or user input.
Every AI request is handled in this order:
1. The local model on our own server (Ollama) is tried first. At this stage
your data does not leave our server.
2. The local model returns an answer together with its own confidence score
(0–1). If the score is above the threshold (default 0.65), the answer is
shown to you as is.
3. If the score is below the threshold, or the local model cannot produce an
answer, the request is sent to an external provider located abroad:
Google Gemini, OpenAI or Anthropic. The order in which providers
are tried is set from the administration panel; if one fails, the next is tried.
4. If no model can respond, you are told "analysis is currently unavailable."
The system never fabricates a result and never fills the gap with a guess.
Our local model runs on limited hardware for image processing. For this reason
**plant disease photos are, by default, sent directly to an external provider
abroad** — the local step may be skipped entirely. Read Section 4 before
uploading a photo.
The confidence percentage you see on screen (e.g. "82% confidence") is a
score the model assigns to itself. It is not an independent accuracy
measurement, a laboratory result, or a statistical guarantee.
Treat the confidence percentage as a rough hint about how carefully you should
proceed — not as a basis for a decision.
> WARNING — please read this.
> Your questions and the plant photos you upload **may be sent to servers
> located outside Türkiye** so that an answer can be produced.
| Provider | What is sent | Where it is processed |
| Google (Gemini) | The text of your question, chat history, uploaded photo | Abroad |
| OpenAI | Same | Abroad |
| Anthropic | Same | Abroad |
What is transmitted is the text you write. Your account name, phone number,
Turkish national ID number, IBAN and field boundaries are not sent separately
to external providers — but if you type them into the chat box, they travel as
part of the text.
Do not enter the following into the AI chat, a disease photo description, or
an irrigation note:
When uploading a photo, make sure the frame contains **no faces, licence plates,
signs, addresses or documents**. Capture only the plant, leaf, fruit or soil.

(field records, marketplace, weather, community) continues to work.
Language models sometimes produce **completely fabricated information in a
confident tone**. This is called a "hallucination." A model may invent a disease
name, a non-existent pesticide, an incorrect dosage or a regulation article that
does not exist — and present it as fact.
This is not a malfunction of the application; it is a known limitation of
today's AI technology and cannot be fully eliminated.
| Error type | Example | What you should do |
| Wrong diagnosis | Saying "rust" when it is powdery mildew | Show a sample to an agricultural engineer or laboratory |
| Invented product or dose | A product name that is not on the market, a wrong dosage | Follow the product label only |
| Outdated information | Recommending an active substance whose licence was revoked | Check the Ministry's current list |
| Region-inappropriate advice | Advice valid for a different climate or soil | Consult your provincial/district agriculture directorate |
| Unit or scale confusion | Mixing up decares and hectares, litres and millilitres | Verify the calculation yourself |
| Misreading an image | Wrong reading due to light, shadow or blur | Take a new photo from a different angle |
| Losing context | Forgetting the crop mentioned in your earlier message | Write the full question in a single message |
Plant disease detection is based on visual similarity. The result is clearly
unreliable when:
frost, chemical burn or water stress,
Most viral, bacterial and soil-borne agents **cannot be distinguished from a
photograph**; laboratory analysis is required for a definitive result.
**No AI output in this application constitutes binding advice, an expert report,
a prescription, a licence, a certificate or an official opinion.**
AI output does not replace:

with the label, the label prevails.

For subsidy applications, farmer registry records, licences, certificates,
insurance and incentives, AI output should not even be treated as guidance.
Legislation changes frequently and the model may not be current. Rely on the
announcements of the competent authority.
Satellite indices, weather forecasts and fire alerts in the application come from
third-party sources and carry their own limitations. AI interpretations built
on this data inherit the same limitations.
| Data | Source | Limitation |
| Satellite indices (NDVI etc.) | Google Earth Engine | The image may be days old; cloud, shadow and snow distort results |
| Weather forecast | Open-Meteo | A forecast, with no guarantee of occurrence |
| Fire hotspots | NASA FIRMS | Delayed data tied to satellite overpass times; small fires may be missed |
| Map tiles | Stadia Maps | Boundary and parcel drawings are not cadastral documents |
> Frost, hail, flood, storm and fire alerts do not replace official warnings.
> Where life or property is at risk, rely on official sources — in particular the
> Turkish State Meteorological Service (MGM), AFAD and the emergency
> number 112. The absence of a notification in the app does not mean there is
> no danger, and receiving one does not mean the event will occur.
When satellite imagery cannot be retrieved or cloud cover is high, the
application tells you so explicitly — it does not substitute an estimated number.
Community posts, comments, listings and messages pass through an automatic
filter. This filter also uses AI and can err in both directions:
An automated decision is not final. If your post was blocked unfairly, you
may request human review by writing to [email protected]. You can
likewise report violating content using the in-app report and block user
tools. Reports are reviewed by a human.
The operation of the automatic filter does not remove our notice-and-takedown
obligations under Law No. 5651.

| Record | Contents | Why |
| Chat messages | Your question, the answer text, provider and model name | So you can see your history and continue the conversation |
| Disease analysis | Detected disease, severity, confidence score, recommendation text, source | So your field history can be tracked |

Your chat history and disease analyses are tied to your account; they are
deleted when you delete your account (see the Account Deletion document). The
user link in AI call logs is also removed on account deletion.
How long external providers retain your data on their side is governed by
their own policies; HNKTech cannot determine that period unilaterally. This
is precisely why the "do not type personal data" warning in Section 4 matters.
AI features are provided "as is." HNKTech:
suitable for your specific conditions;
fertiliser costs, rejection of produce due to residues, animal loss,
administrative fines or similar damages arising from actions you take based on
AI advice;
satellite, weather and map services;
missed content by automatic moderation.
The final decision is yours. It is your responsibility to consult a qualified
specialist before acting on decisions concerning spraying, irrigation, planting,
harvesting and animal health.
These limitations do not cover HNKTech's liability arising from its **intent or
gross negligence** (Turkish Code of Obligations No. 6098, Article 115), and they
do not limit the mandatory provisions of Law No. 6502 on Consumer Protection that
operate in favour of consumers. Your statutory consumer rights are reserved.
The application is intended for users aged 18 and over.
In the following situations, do not wait for the application — contact the
authorities directly.
| Situation | Contact |
| Fire, flood, earthquake, danger to life | 112 / AFAD |
| Forest fire | 112 |
| Suspected pesticide poisoning (human) | 112 / National Poison Information Centre 114 |
| Sick or dead animal, suspected outbreak | Veterinarian / provincial-district agriculture and forestry directorate |
| Notifiable plant disease or pest | Provincial/district agriculture and forestry directorate |
If you see an answer from the AI that is wrong, dangerous or fabricated, please
report it — these reports are our main way of correcting the system.
1. Use the in-app Feedback screen. You may attach a screenshot; the app
version, platform and device model are attached to the feedback automatically.
2. Or write to [email protected]. Where possible, include a screenshot of
the answer and the date and time.
Output that poses a serious safety or health risk is reviewed as a priority, and
the relevant feature may be temporarily disabled.
You may exercise your rights under KVKK Article 11 (to learn whether your data is
processed, to request rectification or erasure, to request restriction of
processing, and to object where an outcome to your detriment arises from analysis
by automated systems) via [email protected] or —.
Applications are concluded within 30 days at the latest, pursuant to KVKK
Article 13.
The AI providers, models and confidence threshold we use may change over time. If
a change materially affects the scope, this document will be updated and you will
be informed in the application. If the scope of cross-border transfer expands,
your explicit consent will be requested again.
