Stonekept
Memories. Create your perfect memory.

Stonekept records only during sessions you initiate, and it is your responsibility to get the consent of anyone else whose voice may be captured. Most of the US, Canada, and the UK let you record a conversation you are part of, but all-party-consent regions need permission from everyone present, including California, Florida, Illinois, Maryland, Massachusetts, Pennsylvania, and Washington, and countries such as Germany and France. Use it the way you would any voice recorder: openly, and with consent where the law requires it. This is general information as of June 2026, not legal advice; our privacy policy has the full breakdown.

On your device. Extraction runs 100% on-device through a custom model we trained for memory work. Transcripts and memories live in a local database on your device, protected by the encryption your device already uses. If you choose to sync between your devices, data travels end-to-end encrypted with keys that never leave your hardware. Our servers only ever see ciphertext. Your recordings, transcripts, and memories are never used for training or advertising. The only data we collect is anonymous usage and crash analytics, designed to be content-free, to keep the app healthy, never linked to you, and you can turn it off in Settings.

iPhone 12 Pro or newer with at least 6 GB of RAM (the on-device model needs the headroom), an Apple Silicon Mac (macOS 26 Tahoe is the version we have tested so far), and Apple Watch Series 6 or newer for wrist capture. Older hardware will not run the extraction model reliably, so we do not support it.

By default, no. Chat in the app runs on a local model on your device, and nothing leaves it. On Stonekept Pro you can also connect Claude. Either Claude Desktop on your Mac (no internet round-trip, no Stonekept server in the loop) or claude.ai via the Stonekept broker, which passes along only the memories you chose and never saves them. It keeps a short access record (which tool was used and when), never the content. The connection is something you toggle on or off. Nothing happens automatically.

Yes. Every recording adds to a graph of the people, places, organizations, and topics Stonekept heard, and how they show up together across your memories. You can confirm, rename, or remove any of them, then open a person or a place to pull up everything connected to it. The links come from what was actually said in your recordings, not from us recommending connections. Extraction is assistive; you decide what is true about your life.

Yes. You can export your data and wipe it from your devices at any time. Delete is a real delete, not a soft delete or a support ticket — it removes the underlying memories, transcripts, and embeddings from the device, and from any synced devices the next time they connect.

Because we want everyone to be able to use it. We would rather build something genuinely good and let it earn the upgrade than lock the core behind a paywall. Capture, extraction, and chatting with your memories all run on your own device, so the free tier costs us almost nothing to run beyond software updates. If you love it, Sync across your devices and connecting an external AI are the paid tiers, and they are what keep the project going. And free does not mean you are the product: we never run ads, sell your data, or collect your recordings, transcripts, or memories. Whether you pay or not, your content is processed on your device. On the paid tiers, where it is backed up and synced between your own devices, it only ever leaves as encrypted blobs we cannot read. The free tier is just as private as the paid ones. The only thing we gather is anonymous usage and crash data, designed to be content-free, so we can respond quickly to bugs and keep the app running well. It is never linked to you, never includes your content, and you can turn it off in Settings.

Upgrade inside the app. On iPhone and iPad it is an in-app purchase billed through Apple. On the Mac you pay through Stripe, and a receipt is emailed to you. Wherever you buy, your plan is tied to your Stonekept account, so it works on every device you sign in to.

Yes. On iPhone or iPad, open Memories and go to Settings, Manage Subscription, then Manage in App Store, and tap Cancel Subscription. On the Mac, open Settings, Account, then Manage billing. You keep your plan until the end of the period you paid for, then Stonekept keeps working on the Free plan. Bought on the Mac and changed your mind?
