One sentence is enough to save where something is. Ask later and hear a short answer, which also shows on screen.

Private by design
Read the full privacy policy
Your things stay yours.
We collect as little as we can. Here is what happens to your data, in plain words.
Stored on your phone
Your items, places and photos live on your phone, in an encrypted database where the phone allows it. There is no account, and we keep no copy.
Smart voice sends only what it needs
When smart voice is on, what you say, plus the item names, places and short facts needed to answer, go to Google Gemini. The live conversation goes straight from your phone to Google, with a single use pass from KnowWhere’s server. That server keeps nothing and only counts requests.
Photos are never sent
Your photos stay on your phone. Under Google’s paid terms, what you say is not used to train its models.
You are in charge
Turn smart voice off and your phone’s own speech recognition is used instead. Delete everything in Settings, then Your data, then Delete all my data. KnowWhere is for adults aged 18 and over.

What is KnowWhere, in one sentence?
KnowWhere is a free voice assistant for Android that remembers where you put things: say where something is, in English, Hindi or Urdu, ask when you forget, and get reminders that say where it is. See how it compares with trackers, notes apps and inventory apps.
Is KnowWhere free, and does smart voice cost anything?
Yes, KnowWhere is free to download, with no ads and no in-app purchases. Smart voice is part of the free app. To keep it available for everyone there is a daily limit for each phone; when it is reached, KnowWhere uses your phone’s own voice until the limit resets, and typing always works.
Does Aatox see what I save?
No. Your items, places and photos are stored on your phone, in an encrypted database where the phone allows it, and we keep no copy. When smart voice is on, what you say plus the item names, places and short facts needed to answer go to Google Gemini. Photos are never sent. KnowWhere’s server keeps nothing and only counts requests. The privacy policy has the full text.
