SovaSpace is an encrypted space for private work — writing, files and media in one place, stored in your own Google Drive, not on our servers. Everything is encrypted on your device before it leaves.
START WITHOUT COMMITTING ANYTHING
• Sign in with Google. No second password, no registration form.
• A 7-day evaluation starts with your first Entry, covering up to 14 active Entries.
• No payment card is requested.
• It does not become a paid subscription by itself. Nothing is charged unless you choose.
• If you later stop paying, viewing, export and sync stay open — only creating and expanding are gated.
YOUR DATA IS ACTUALLY YOURS
• End-to-end encrypted by default: titles, text, tags, attachments, subtitles, annotations and the local database.
• Stored in your own Google Drive. Our service sees account and sync metadata — never Entry contents or attachment bytes.
• No ads, no trackers. Your content is not sold and does not train a generative model.
• Export to Markdown or PDF, and take plaintext attachments, any time.
• Local-first: Entries open and edit without waiting for Drive; offline edits sync later.
WHAT OPENS INSIDE IT
• 70+ file extensions: PDF, EPUB, DOCX, XLSX, PPTX, DICOM, DXF, PSD, SQLite, Jupyter, Anki, XMind, 3D models, fonts, archives, source code.
• Search inside an open file — documents, spreadsheets, code, data — reports when a result is incomplete instead of returning zero.
• Closed proprietary formats are declined with a reason and a suggested export format.
ANNOTATE WITHOUT DAMAGING THE ORIGINAL
• Highlights, pen strokes, shapes and bookmarks — each carries a short summary and a full illustrated note.
• Marks work on scanned pages, no OCR.
• Annotations live in a separate encrypted sidecar; the source file is never rewritten.
• EPUB uses a fixed layout, so pages and annotations land identically on every device.
BUILT FOR REAL FILES AND REAL NETWORKS
• Large uploads resume from the byte they stopped at. Close the app, lose the network, reboot — nothing starts over.
• Encrypted cloud video seeks in ranges without downloading the whole file.
• No plan-based attachment size limit — Drive quota and device storage are the limits.
MEDIA YOU CAN WORK WITH
• Subtitles in seven formats (SRT, VTT, ASS, SSA, LRC, SUB, SMI) with search, click-to-seek, language tracks, and a Focus Mode that repeats a pinned line.
• Audio recording and playback.
• Web capture downloads a page's images and encrypts them as your own copies, so an old clipping still shows them.
ONE OR TWO PRIVATE SPACES
• Each Secret Space has its own password, keys and Recovery Key. Tactical Mode configures two; the shared reminder never says which exists.
• Switch away from the app and the Secret Space closes itself.
• Forgot one? Use your Recovery Key, or a protected reset after a waiting period you choose. Support cannot read your content.
THINK IN LINKS
Rich text, tables, tags with global rename and merge, wiki links, backlinks and a knowledge graph. (Standard Space only.)
WHEN SOMETHING GOES WRONG
• Trash keeps Entries for 30 days.
• Windows Cold Backup opens read-only and offline, independent of any Drive copy.
• Device history, trusted-device control, sign-in review; one session at a time.
• A failed task stays visible and retryable, never shown as done.
HONEST ABOUT WHAT IT DOES NOT DO
• Some formats are view-only; results depend on a file's version and complexity.
• Secret Spaces do not defeat screenshots, keyloggers, or an already-unlocked device.
REQUIREMENTS
A Google account is used for sign-in, trusted-device setup and Drive access. Encrypted objects use your Drive quota; local copies use device storage. Camera, photos, microphone and notifications are requested only when used.
Windows and Android are available today. Apple platforms are planned, not available.
