WhiskerCheck Terms of Use

Last updated: 10 October 2026.

1. What this is and who offers it

WhiskerCheck is an app that looks up whether something is documented as dangerous for dogs and cats — because it poisons, or because it chokes or blocks. It is offered by Miguel Gamarra, an individual, with address at Proviv. Res. La Esperanza, Carabayllo, Lima 15121, Perú, and contact at contact@whiskercheck.com.

By using the app you accept these terms. If you do not accept them, do not use it.

2. The only thing it does, and what it does not do

WhiskerCheck is a reference source, not a vet.

It does not diagnose. It knows nothing about your animal beyond the species and the weight you have told it, and it cannot know how the animal is.
It does not treat. Nothing it says replaces a veterinary consultation.
It is not an emergency service. If your animal has eaten something, call your vet or an animal poison control centre. Do it even if the app says there is nothing wrong.

The toxicity data comes from public veterinary sources — ASPCA, Pet Poison Helpline, Merck Veterinary Manual and equivalents — and every result cites its own so that you can check it. This is a compendium of those sources, not a clinical opinion of our own, and no vet has reviewed the database.

3. The limits, stated plainly

We would rather you knew where it fails than have you find out the hard way:

A green result does not mean that something is safe. It means that we found no known danger in what you scanned. It may contain something that is not in our database, or the label may be incomplete or misread.
Some answers do not come from our database, but from a language model. When what was scanned is not documented, we ask a model and the screen says so: that answer is marked and comes with no source cited, because it has none. A model gets things wrong in different ways than a record does, and that is why it is set apart on screen instead of being mixed in with the rest.
Identification can fail. Barcodes come from a collaborative database that can have errors. Labels and photos are read by an automatic system that gets things wrong, especially in bad light or with things that look alike.
The database is incomplete. It covers the best-documented substances, not every one that exists.
Amounts are a guide. If you say how much it ate, the calculation uses published thresholds and an estimate of yours. It is guidance, not a measurement.
It does not cover other species. Only dogs and cats. For a rabbit, a bird or a ferret, it is no use.

4. What is on you

Using the app as support and not as a substitute for a vet’s judgement.
In an emergency, calling a professional, without waiting for the app or relying on it.
Not using it to make decisions affecting an animal’s health without checking elsewhere.
Not trying to take the service down, get around the usage limits or extract the database in bulk.

5. Liability

The app is offered as is. We take care that the data is correct and that each piece cites its source, but we do not guarantee that it is complete, up to date or free of error, nor that the app is always available.

The decision is yours. WhiskerCheck gives you information so that you can decide what to do; what you decide and what follows from it is your business. To the extent that the law allows, we are not liable for damages arising from using the app or from not being able to use it, nor for those arising from data that is incorrect, incomplete or wrongly identified.

What is never excluded: liability for willful misconduct or gross negligence, liability affecting people’s life or physical integrity, and any other that the applicable law does not allow to be excluded.

And if you are a consumer, you keep in full the rights your country’s law gives you, with nothing in this document limiting them: in the European Union, consumer law; in Brazil, the Consumer Defence Code, whose article 51 voids any clause that lowers the supplier’s liability; in Peru, the Consumer Protection and Defence Code.

And a warning that is not legal but practical: in an emergency, call the vet before opening the app.

6. In-app purchases

WhiskerCheck is used free of charge with five scans. To scan without a limit there is WhiskerCheck Pro, a subscription with two plans, monthly and yearly; the yearly one starts with a free week.

Those five come with three conditions worth knowing beforehand rather than afterwards:

They are for life, not per month. Once they run out, they are gone.
They belong to this installation, not to you and not to your Apple account.
They do not reset when you reinstall the app or when you use “Erase everything on this phone”: the counter lives in the iPhone’s Keychain and survives both. It is explained in the privacy policy.
The store shows the price in your currency before you confirm, and it changes by country. If we raise it, the store tells you before the next renewal.
It renews itself at the end of each period, unless you cancel it at least 24 hours before it ends.
You cancel it in the store, not here: on iOS, Settings → your name → Subscriptions. Cancelling stops the renewal; what you already paid for stays active until it runs out.
Apple handles the charge — and Google the day there is an Android version — under their own terms, and refunds are requested from them, not from us. We never see your payment method at any point.
Who checks that you have paid: we use RevenueCat to validate the Apple receipt and to know whether your subscription is still active. What it sees, and what it does not, is in the privacy policy.
“Restore purchases”, on the paywall and in Settings, gives you back a subscription you already paid for: when you change phones, or if something gets lost. It charges nothing.
Right of withdrawal in the European Union: digital content is delivered immediately, and by purchasing you agree that performance begins before the fourteen days are up and that this right is extinguished with it. The store asks you for this expressly at that moment.
Right of regret in Brazil: article 49 of the Consumer Defence Code gives you seven days to withdraw from a purchase made off-premises, and that cannot be waived. The point above is the European rule and does not touch this right.

The emergency is never paid for. The sheet on what to do now and the poison control phone number are outside the paywall, and that is where they stay.

7. Reporting an incorrect result

Every verdict screen has a button to tell us that something is wrong. Use it: it is the way the data gets corrected. What you send we use to review and correct the database.

8. Ownership

The app, its code and the way the database is organised are ours. The toxicity data comes from the cited sources and belongs to their authors.

9. Changes and end of the service

We may change these terms; the date at the top will say when. If the change is important, we will say so in the app. We may stop offering the service, giving reasonable notice if there are active subscriptions.

10. Governing law

These terms are governed by Peruvian law, and for anything that is not a consumer matter the courts of Lima, Peru have jurisdiction.

If you are a consumer, this takes nothing away from you. You keep the protection of the mandatory rules of the country where you live and you can bring a claim before the courts of your own domicile. In the European Union this is guaranteed by Regulation (EU) 1215/2012; outside it, whatever your country’s consumer law says.
