Privacy Policy
Version of 10 November 2026
Dietalog is a personal dietitian in Telegram: the bot @counter_fat_bot and the app inside it. This page explains in plain words what data we keep, why we need it and how to delete it.
In short. We keep only what is needed to run your food diary. We do not sell data and we show no ads. We will delete everything at your request: hello@dietalog.com.
Who is responsible for your data
The Dietalog service. For any question about your data, write to hello@dietalog.com — we reply within 30 days.
What data we keep
- From Telegram: your account identifier, name and language. We do not receive your phone number.
- What you tell us about yourself: sex, age, height, weight, goal, steps, time zone.
- Your diary: what you ate (names, grams, calories, protein, fat, carbs), weigh-ins, steps and workouts.
- The dietitian’s memory: your usual dishes and portions, notes about your habits, and health details — only those you mentioned yourself.
- Your meal plan: your answers to the dietitian’s questions and the plan itself.
- Reminders you asked us to set.
- Your conversation with the dietitian: the text of your messages and of the replies.
- Service records: request times and error messages.
What we do not keep. Food photos and voice messages: a photo is sent for recognition and is not saved; a voice message is turned into text and deleted right away. We hold no payment data.
Why we need it
- to count your food and keep your diary;
- to work out your daily target and build your meal plan;
- to send reports and reminders;
- to remember what you have already said, so we do not ask again;
- to find and fix the dietitian’s mistakes — for this, conversations may be read by the Dietalog team and by an automated quality check.
The basis is your consent and the fact that the service cannot work without this data. We process health details only because you shared them yourself, and only to count and advise more carefully. You can ask us to delete them at any time.
Who we share data with
To answer you, the dietitian calls outside services. Each one receives only what a particular answer requires:
- Telegram — delivers messages and opens the app.
- Anthropic (Claude models) — your message or food photo, and the diary data needed for the answer.
- OpenAI — live voice conversation in the app: the sound of your voice and the text of the replies.
- ElevenLabs — the text of a reply that needs to be spoken.
- Open Food Facts — a product barcode, if you scan one.
- Cloudflare — delivers the pages of the site and the app and sees technical request data such as your IP address.
- Google — email, if you write to hello@dietalog.com.
Some of these companies are based in the United States, so your data may be processed outside your country. We do not sell data, do not pass it to advertising networks and do not use it for advertising.
How long we keep data
For as long as you use Dietalog. If you ask us to delete your data, we will do so within 30 days.
Your rights
- See what the dietitian remembers about you: the /memory command in the chat, or the “What I know about you” section in the app.
- Correct it: tell the dietitian — for example, “forget that I don’t eat fish”.
- Delete a diary entry: tap it in the app, or write “undo last”.
- Delete all your data or get a copy: write to hello@dietalog.com and tell us your Telegram name.
If you live in the European Union, you also have the right to contact the data protection authority of your country.
