Common Questions

Do I need an account?

Only for Resetra. HelveTalk and AquaDry work fully offline and do not require an account — just download and start; they never contact a server of ours. Resetra lets you create an account with Sign in with Apple or Google so your data can be backed up and restored across devices. Signing in is what enables backup; without it, Resetra also stays entirely on your device.

Why does AquaDry ask for microphone or camera access?

Both are optional and only used by AquaDry's Sound Meter. The microphone measures the ambient sound level (in decibels) in real time on your device — no audio is recorded or uploaded. The camera can show a live preview behind the meter so you can point the phone at what you are measuring — no photos or video are captured, saved, or uploaded. The water-eject cleaning tones themselves need no permissions at all. You can decline both and still use AquaDry to clean your speaker; you can change these anytime in your device Settings.

AquaDry didn't remove the water — what should I do?

AquaDry is a helper utility, not a repair service, and results vary by device. Turn the volume up, remove any case, and hold the phone with the speaker facing downward while a program runs; longer programs and a second pass often help. If your device was exposed to a lot of liquid, power it off and consult the manufacturer or a qualified repair service — do not rely on any app for the safety of your device.

Which apps send my data anywhere?

Only Resetra, and only if you sign in. Resetra uses Supabase for sign-in and for an encrypted backup of your progress — your backup is encrypted on your device with AES-256 before it is uploaded. HelveTalk and AquaDry use no Supabase and have no Nestlava backend at all: their lessons, words, streaks, settings and cleaning history never leave your phone.

Is AquaDry's Sound Meter accurate?

It is an estimate, not a calibrated measurement. The reading comes from your phone's microphone, which varies by device and is affected by cases, wind and how you hold the phone. It is genuinely useful for comparing one moment or one room to another, but please don't use it for workplace, legal, safety, or health decisions.

How loud should I run the tones?

For water eject and deep clean, turn the volume up and hold the phone with the speaker facing downward — the tones need real output to move water. But keep the phone at arm's length and away from your ears, other people, and pets, especially during Dust Eject and the Frequency Generator, which are deliberately loud. Stop straight away if it sounds uncomfortable.

How do I manage or cancel a subscription?

Subscriptions are billed by the app store, not by us. To manage or cancel:

Cancelling stops future renewals; you keep access until the end of the current billing period.

How do I restore my purchases?

If you reinstalled an app or switched devices, open the app's settings and choose Restore Purchases. Make sure you're signed in to the same Apple ID or Google account you used originally.

How do I request a refund?

Refunds are handled by the app stores. For Apple, visit reportaproblem.apple.com. For Google Play, request a refund from your Play Store order history. If you have trouble, email us and we'll help where we can.

How do I back up or restore my data?

Resetra is the only app with a backup: sign in and your data is encrypted on your device and backed up, then restores automatically when you sign in on a new device. HelveTalk and AquaDry store everything on your device with no cloud copy, so their data does not carry over to a new phone — and uninstalling removes it for good.

How do I delete my account and data?

In Resetra, open the app's settings and choose Delete Account, or email us at info@nestlava.com and we'll delete your account and associated cloud data. For HelveTalk and AquaDry there is no account and nothing stored on our side — uninstalling the app deletes everything.

My notifications or reminders aren't working

Make sure notifications are enabled for the app in your device settings, and that reminders are turned on inside the app. On some devices, battery-optimization settings can delay scheduled notifications.

Found a bug or have a feature request?
