WEAVEN stores your profile, chart, conversations and settings in your account; sends the AI provider only the current message, the selected profile's calculated chart, approved memories and recent turns, and only after your consent; deletes readings photos after processing unless you keep them; sets no advertising or analytics cookies; and lets you export or delete everything yourself from the Account screen.

Who is responsible
WEAVEN 天纹 is operated by Ejoshi Software Inc. This page describes the WEAVEN web application at weavan.app/app and this website.
What is collected
| Data | When it is created | Where you control it |
|---|---|---|
| Guest session | When you start as a guest, an anonymous account is created for your browser. No email or phone is involved. Sign-in state is kept in the browser's local storage. | Clearing site data ends the session; creating an account attaches the same data to it. |
| Account identity | Email address and password, or a Google sign-in, or a phone number with an SMS code. | Account screen: sign in, sign out, create account from guest. |
| Birth profiles | Name or label, relationship, date (Gregorian or lunar), time or time range, birthplace, coordinates, time zone, optional gender, dominant hand, notes, preferred language. | Profiles screen: edit or delete; deleting a profile deletes its charts. |
| Calculated charts | Stored with the calculator name, version, method, input snapshot, warnings and confidence. | Recalculate or delete with the profile. |
| Conversations and messages | Your messages, the replies, the mode used, model and provider names, token usage, latency and any safety flags. | History drawer: rename, archive, delete. |
| Photos for palm or face readings | Only after explicit consent. Checked for format, stripped of EXIF/XMP metadata, stored in a private bucket, processed once and deleted afterwards by default. | Account → Images: default handling ("process once" or "save privately") and deletion of kept images. |
| Memories | Nothing is remembered automatically. Items you add, and only with the memory consent switched on. | Account → Memory: add, edit, delete, clear all, switch off. |
| Saved readings, feedback, preferences | Readings you save; helpful/not-helpful votes with optional reason; language, appearance, reading perspective and reply-language settings. | Account screen. |
| Usage counts | Daily and per-minute message and image counts per plan, used to enforce limits. | Shown on the Account screen. |
| Local browser data | Preferences, the consent record, the journal and sample-map progress from the older prototype, the guest reminder flag. | Account → Export local data / Delete local data. |
What is sent to the AI provider, and when
Replies are generated by a large language model from Anthropic through its commercial API. Nothing is sent before you tick two boxes on the consent sheet (18 or over; agreement to the processing). For each message the app sends: the message itself, a compact summary of the selected profile's calculated chart, memories you have approved, the recent turns of the current conversation within your plan's history limit, and, for palm or face readings, the verified photo. It does not send other profiles, other conversations, your email or phone, or your journal.
The provider's commercial terms state that API inputs and outputs are not used to train its models; see Anthropic's commercial terms. WEAVEN itself does not train models on your data. WEAVEN's interface names the assistant WEAVEN; if you ask which company's model is behind it, it answers truthfully.
Where data lives
Account data, profiles, charts, conversations, memories and photos are stored with Supabase (database, authentication and private file storage) in the United States (us-east-2 region). The web application is served by Railway. All traffic uses HTTPS. Database rows are protected by row-level security so that every query is scoped to the signed-in user, guests included; provider keys are held server-side and never reach the browser.
Retention
- Profiles, charts, conversations, memories and saved readings are kept until you delete them or delete your account data.
- Photos are deleted after processing unless "Save privately" is chosen; kept photos stay until you delete them.
- Guest sessions belong to the browser they were created in; if the browser's storage is cleared and no account was created, the data becomes unreachable and is not recoverable.
- Usage counts are kept for limit enforcement and aggregate health statistics; they contain no message content.
Your controls
- Export. Account → "Export account data" downloads everything the app holds for you as a JSON file. "Export local data" does the same for browser-local data.
- Delete. Account → "Delete account data" permanently removes your profiles, charts, conversations, photos, readings and memories from WEAVEN's servers. The sign-in itself remains until an administrator removes it: email hello@weavan.app to close the login as well.
- Consent. The consent record can be withdrawn on the Account screen; you will be asked again before the next message.
- Memory and images. Switch memory off or clear it; choose "process once" for photos; delete kept photos.
Cookies, analytics and this website
The app keeps your sign-in and preferences in the browser's local storage, which is essential for it to work. Neither the website nor the app sets advertising cookies, uses third-party analytics or embeds social widgets. Links from this website into the app carry a short source label (for example "site-home-hero") so that the operator can count in its own server logs how many visits turn into app openings; the label contains nothing about you.
Safety and sensitive topics
If a message suggests you might be at risk, WEAVEN shows crisis resources first and stops the reading. Replies that would diagnose, predict a death, guarantee an outcome or infer personal traits from a photo are rewritten by a server-side validator. Birth details, relationships and personal questions are treated as sensitive information throughout.
Children
WEAVEN is for adults 18 and over. The consent sheet asks you to confirm this before the first message.
