How can we help?

No. The whole app works without an account or password. The account is optional, for people who want a cloud copy and sync between phones, on any plan, Free included. To sign in, use your Google account, with no password at all. The session is kept in your phone’s secure storage.

Yes, all of it. Everything is stored on the phone, so you can record clients, quotes and jobs without signal. Schedule reminders work offline too. Only the cloud copy needs a connection to sync.

On your phone. No one at Nerolith reads it. On any plan, if you sign in, a copy is kept in the cloud, isolated by account. The copy carries clients, quotes, jobs, expenses, your team and your business details (name, trade and Pix key). Photos and logos never leave the device.

On any plan, sign in to the same account on the new phone and the copy downloads by itself. Photos and logos are not included: the job shows up as usual, with a “Foto não está neste celular” (photo not on this phone) note where each photo was. You can also make a backup file and take it to the other phone. Without a cloud copy or a backup, the data lives only on the device.

On any plan, tap Falar (Talk) and describe what you did. Your phone’s own speech recognition (Google’s, on Android) turns the audio into text, in Portuguese, and may process the audio on Google’s servers. Mestre only receives the text and builds the job, quote, client or expense for you to check.

No. The app builds the Pix copy-and-paste code and QR code on the phone itself, with your key, offline. The client pays you directly. Get paid by Pix is on every plan. With your account connected, your Pix key goes in the cloud copy, along with your business details.

No. Amounts and reports are calculations from what you enter. They are not invoices or accounting documents.

Through your phone’s app store. Cancelling applies to future charges, the paid period stays active and no data is deleted.

Every feature is on every plan. What changes is the limit: on Free, 25 clients, 30 jobs and 30 quotes; on Pro, 150 clients, 600 jobs and 600 quotes; on Chefe, 1,000 clients, with unlimited jobs and quotes, plus the team feature and priority support. When you reach a limit, everything already saved stays there to view, edit and export. Anyone who subscribed to the old Max plan now has Chefe.

In Configurações (Settings), use Apagar todos os dados (Delete all data). With your account connected, the cloud copy is deleted too. To delete the account as well, go to Mais › Configurações › Excluir minha conta (More › Settings › Delete my account). Without the app installed, use the Delete account page.

You sign in with your Google account, with no password for Sólida. We keep the email and name Google sends at sign-in and an internal account ID, hosted on Supabase.

On your phone: your profile, health notes, workouts, loads, check-ins and foods. Only the account leaves the device. Health data is only processed with your consent, given on the sign-up screen, and Nerolith doesn’t use it for advertising or sell it.

Not today. Lia runs on your device, without artificial intelligence, and your messages are not sent to any server. She doesn’t diagnose: for severe pain, shortness of breath or unusual bleeding, seek medical care.

No. Sólida is not a medical service and does not diagnose, prescribe or treat. The training program, the light version, the tips and Lia’s answers are general guidance and don’t replace a doctor, physiotherapist or trainer. The app is for people over 18 only.

You get 7 free days. If you don’t cancel before the trial ends, billing starts on its own: R$ 34.90 per month or R$ 199.90 per year. Google Play handles billing, and Nerolith never receives payment details. To cancel, go to the Play Store, under Payments and subscriptions: it applies to future charges, and you keep access until the end of the paid period. Uninstalling the app or deleting your account does not cancel the subscription.

You can withdraw from your first purchase within 7 days (art. 49 of Brazil’s Consumer Protection Code) by asking Google Play for a refund. If you have trouble, write to support.

On the Evolução (Progress) screen, tap the button to generate the report. The PDF is made on your phone and only leaves it if you share it, for example by WhatsApp, email or Drive.

In Sólida, go to Perfil › Excluir minha conta e meus dados (Profile › Delete my account and data) and confirm. This deletes your profile, workouts and health records, and can’t be undone. Without the app installed, use the Delete account page (in Portuguese) or write to support. Deleting the account does not cancel the subscription: cancel on Google Play first.
