Privacy
The calculations happen on your device. To improve the model, questions typed in smart mode are saved anonymously unless you turn that off. We do not use cookies.
What stays on your device
The percent-nlu model runs in your browser, so answering your question never needs a server. Numbers you type into the classic calculators are not saved.
What is saved to improve the model
When you ask a question in smart mode, and unless you turn it off, we save:
- the question as you typed it, with e-mail addresses, phone numbers and other long digit sequences masked before it leaves your browser;
- the model's answer (calculation, numbers, confidence) and the model version;
- your feedback, if you give any: ✓/✗, a number or calculation you corrected, or the classic calculator you used right after;
- the page language and a random session id that changes every 24 hours.
We do not save your IP address, your browser's user agent, an account or anything that identifies you. The data is used only to find questions the model gets wrong, build new test sets and train future versions of percent-nlu. It is stored with our database provider (Supabase) and kept for up to 24 months.
If you are in the EU, EEA, UK or Switzerland, nothing you type is saved unless you choose “Allow” under the question field.
Usage statistics
We count anonymous events such as page views, which calculation was used, whether smart mode understood the question and how long it took, without the text you typed. We also use Vercel Web Analytics and Speed Insights for aggregated page views and page speed; they do not use cookies.
Turning it off
Use “Turn off” under the question field. The choice is remembered in your browser's local storage; with it off, only the anonymous usage statistics above are sent.
Deleting your data
Your current session id is not set. To delete what was saved under it, open an issue on GitHub
with the id. Because the id is random and changes every day, we cannot link it to you in any other way.
Em português
Os cálculos acontecem no seu aparelho. Para melhorar o modelo, as perguntas digitadas no modo inteligente são salvas de forma anônima, com e-mails, telefones e sequências longas de dígitos mascarados, junto com a resposta do modelo, sua correção (se houver), o idioma da página e um identificador aleatório que muda a cada 24 horas. Não guardamos IP, user agent nem nada que identifique você. Os dados ficam no Supabase por até 24 meses e servem só para avaliar e treinar novas versões do percent-nlu.
Para não participar, toque em “Desativar” abaixo do campo de pergunta. Para pedir a exclusão, abra uma issue no GitHub com o identificador mostrado acima. Na União Europeia, EEE, Reino Unido e Suíça, nada é salvo sem você tocar em “Permitir”.
