Help center

Everything starts from the home page calerys.com. You click on “Start for €1”, you pay €1 to activate your 7-day trial, and you receive a welcome message on WhatsApp immediately. You start chatting with Calerys a second later.

Calerys uses an official WhatsApp Business number. You receive it automatically after signing up. Save it in your contacts to find the conversation easily.

Yes, as long as WhatsApp is available in your country. The interface and recommendations are currently in English and French. German will arrive soon.

No. Calerys lives inside WhatsApp, which you probably already have installed. No other installation is required.

Check your “Message requests” or “Spam” folder in WhatsApp. If there's nothing there, write to hello@calerys.com with your phone number and we'll activate you manually.

€1 for the first 7 days, then €14.90/month (monthly) or €111/year (yearly, equivalent to €9.25/month). You choose the plan when signing up.

If you haven't done anything, your subscription automatically rolls over to the plan you selected on day 8. You can cancel at any time before that date — just send stop to Calerys on WhatsApp.

You can access the Stripe portal via the link in your subscription confirmation email, or by sending billing to Calerys on WhatsApp. Stripe lets you update your card securely.

Yes. Send change plan to Calerys on WhatsApp, or write to hello@calerys.com. The change takes effect at the next billing date.

Your invoices are available in the Stripe customer portal (link in your confirmation email). You can also write to hello@calerys.com.

Never. We do not sell any data, to anyone, in any case. No data broker, no advertising retargeting, no sharing with advertisers. See our privacy policy.

Your data is stored encrypted on Supabase, on servers located in Frankfurt, Germany (EU). Encryption is AES-256 at rest and TLS 1.3 in transit.

Send delete account to Calerys on WhatsApp, or write to hello@calerys.com. Your data is erased within 30 days, except invoices (kept for 10 years for Swiss accounting obligations).

Yes. You have a right to portability (GDPR article 20). Write to hello@calerys.com mentioning “portability” and we'll send you a JSON export within 30 days.

No, except in two cases: (1) you ask us for help on a specific issue and authorise us to look at the context; (2) occasional quality audit by our scientific committee on strictly anonymised conversations.

You can describe your meal with a text message (“a plate of carbonara pasta”) or send a photo. Calerys identifies the ingredients, estimates the portions and calculates the calorie and macronutrient intake. The estimates are indicative — the margin of error on a single photo is typically 15 to 25%.

Yes. Tell it what you have in your fridge, or what you feel like eating, and it will suggest ideas tailored to your goals and constraints.

Yes. Mention your allergies and intolerances during onboarding or at any time. Calerys takes them into account in its recommendations. However, in case of a severe allergy, never rely solely on Calerys's analysis: check the labels and consult your doctor.

Calerys can help you better understand what you eat and adjust your intake according to goals you define. It is not a substitute for medical or dietary follow-up, in particular if you are considering significant weight loss, if you have a medical condition, or if you suffer or have suffered from an eating disorder. In those situations, consult a healthcare professional first.

As you like. Some users write at every meal, others once a day, others only when they have a question. Calerys adapts to your rhythm — with no guilt-inducing notifications.

Three ways:

• Send stop or cancel to Calerys on WhatsApp.
• Go to the Stripe customer portal via the link in your confirmation email.
• Write to hello@calerys.com.

Cancellation takes effect at the end of the current period. No fees, no justification required.

No, not immediately. Your account stays dormant for 90 days after cancellation, so you can come back easily. After that, the data is deleted (unless you request immediate deletion).

The 7-day trial at €1 acts as a satisfaction guarantee. Beyond that, no pro-rata refund is owed in case of mid-subscription cancellation, except where mandatory law provides otherwise. For a specific case, write to hello@calerys.com — we look at each request in good faith.

Yes, easily. As long as your account is still dormant (90 days), you get all your history back. After that, it's a new sign-up, but we offer a welcome discount to returning users on request.

Three things to try: (1) check that your subscription is active (send status); (2) restart WhatsApp; (3) write to hello@calerys.com specifying your number and the approximate time of the last message sent.

It happens. Estimating from a photo is imperfect by nature. Correct Calerys directly in the conversation (“no, it was more like 200g of rice”) — it updates its analysis in real time and learns from your corrections over the long run.

Check that the photo is sharp and well lit, and that the food is clearly visible. Try again. If the problem persists, write to hello@calerys.com.

That's normal: for technical reasons tied to WhatsApp Business, the “seen” indicator doesn't always reflect Calerys's actual activity. If you don't get a reply to a message within a minute, write to us.
