Privacy
Last updated: 1 October 2026
Weavify is a private diary for iPhone, iPad and Mac, and in a browser at app.weavify.in. There is no account, no sign-up, and no tracking. Your entries are stored only on your device — in the app's own storage on iPhone, iPad and Mac, and in your browser's local storage (IndexedDB) on the web. We don't have a copy.
One exception, stated plainly because it is the kind of thing this page exists to state: if you use the free tier, our relay gives your copy of the app a random number so it can count that copy's share of the daily allowance. It is not an account and it identifies nothing about you. What it is, exactly →
What leaves your device depends on which engine writes the replies:
On-device model stays on device
On iPhone, iPad and Mac, with Pro, the AI model runs on the device itself. Your entries are never sent anywhere, and the diary works with no internet once the model has downloaded. The web version has no on-device model.
Your own key (BYO) your account
The app talks directly to the AI provider you chose (e.g. OpenAI, Anthropic, a local server), using the key you entered. That key stays on your device — we never see it, and nothing passes through our servers.
Free tier leaves your device
The free tier is the default, and it is a convenience we fund so you can use Weavify without a key. When it is active, requests pass through our small relay, which adds our operator key and forwards them to OpenRouter (an AI routing service). Two kinds of content are sent this way:
- Your entry and its context — what you wrote, and the memory and recent entries the reply needs.
- Document / memory text (embeddings) — if you index a document or let Weavify build searchable memory on the free tier, that text is also sent to OpenRouter to be turned into embeddings.
We do not store the contents of your entries or documents on our server; they are relayed to OpenRouter to generate a response and then discarded. For replies, we ask OpenRouter to use only providers whose policy is not to store or train on the request. OpenRouter and the model providers process the request under their own terms. If you want nothing to leave the device, use the on-device model or your own key.
The free tier keeps a counter, not an identity. The free tier has a daily allowance, and it has to be shared out somehow — otherwise one heavy day for one person uses up everyone's. So the first time you use it, our relay gives your copy of the app a random number and your app remembers it. It is used for one thing: counting how much of the allowance that copy has used today.
It is not an account and it has no password. It is not linked to your name, your email, your phone number or your location, and it is not built from anything about your device or browser — the relay picks it at random, so two copies of the app on the same device get different numbers. It tells us nothing about what you wrote; your entries are never stored on our server. It cannot be matched to you on any other site. It is never sent when you use the on-device model or your own key. Uninstalling the app, or erasing your data in Settings, throws it away — and you simply get a new one next time.
Other things that can leave your device — only if you turn them on
Online natural voice reply text only
If you choose the online natural voice, the reply is sent to Weavify's voice service to be spoken and comes back as sound. What you wrote is never sent, and nothing is kept. The on-device voices send nothing.
Better dictation (iPhone, iPad and Mac) audio to Apple
If you turn on better dictation, what you say is sent to Apple to be turned into text, under Apple's terms. Weavify never receives the audio.
Reporting a reply only when you tick the box
A report is written down on your device first. It is sent to us only if you tick the box that says so — and then it carries the reply and the entry it answered. We use reports only to find and fix bad replies. They are not linked to you, and they are deleted after at most 90 days.
Purchases handled by Apple
Apple takes the payment; we never see your payment details or your Apple Account. To give a subscription its daily allowance, our relay checks the receipt Apple signed and keeps a one-way scrambled form of the purchase's transaction number as the counter for that allowance. It is not linked to your name or account, and it is never shared.
Downloaded models
The on-device model and the on-device voices download their files from public content-delivery networks (such as Hugging Face) the first time you use them. Those are ordinary file downloads; your entries are not included.
On the phone apps, the first on-device download also asks our relay once for the read key that unlocks the model files. That request carries no counter, no identifier and nothing you wrote — it is a request for a key, not for a reply — and the model files themselves come straight from Hugging Face, not through us.
What we never do
- No accounts, no advertising, no analytics profiles, no selling data.
- We never log the contents of your prompts, notes, or documents on our server.
- Your BYO API key is never transmitted to us.
- The free tier's counter is never used to build a profile, never shared with anyone, and never sent on the tiers that don't use our relay.
