Thanks everyone for joining — let's start with the portfolio review.
00:27
Equities are up but I'm wary of rate volatility next quarter.
00:41
…so for the next quarter I'd like to shift roughly ten percent out of equities and into short-duration bonds.
The privacy contract
Seven promises. No exceptions.
These are the product. They hold in v1 and every version after. Each one is verifiable in code or in the manifest — not a marketing claim.
02
Encrypted at rest
Transcripts and minutes are stored in a SQLCipher-encrypted database. Audio files are AES-256-GCM encrypted.
03
Zero outbound network calls
The core app makes no outbound network calls carrying your content. No telemetry, no analytics, no "anonymous" launch counters. The one network use is the opt-in, Wi-Fi-gated AI model download from huggingface.co — it never uploads your data.
04
Exports are explicit
Every export is user-initiated and shows a confirmation screen with the content and destination before anything moves.
05
No account, no sync, no login
There is nothing to sign up for. Your minutes do not belong to a cloud account because there is no cloud account.
06
Open architecture
A plain-English architecture page explains exactly what runs where, with the network manifest you can verify yourself.
Read the architecture →07
Privacy-critical code is open source
Recording, encryption, key management, and the network manifest are published on GitHub under a permissive license.
View on GitHub → On-device, end to end
Every screen here runs with the network off.
Recording, transcription, and minutes generation all happen on your phone — swipe through the actual flow and notice what's missing: any sign of the cloud.
What's inside
The mechanics. Without the marketing.
Every feature exists to support a regulated professional doing real work. No bots, no calendar scraping, no auto-join — just a recorder, a transcriber, and a minutes generator that stay on your phone.
Single-tap recording
One tap to start. Recording continues with the screen off and survives incoming calls. Auto-save every 30 seconds.
Configurable consent prompt
Off, verbal capture, or silent confirmation. Includes a built-in guide to one-party and two-party consent jurisdictions.
On-device transcription
Whisper runs locally on your phone, during and after recording. The base English model ships with the app. No audio uploaded, ever.
Live transcript, optional
An opt-in pull-up sheet shows the transcript building as you speak. The calm recording screen stays the default — reach for the live view only when you want it.
Four minutes templates
Client Meeting Minutes, Decision Register, Action Items with Owners, and General — each led by a short summary. On-device AI (Gemma 4 E2B) writes them, with a template fallback. Edit before exporting.
Encrypted local storage
SQLCipher-encrypted database, AES-256-GCM audio files, key in Android Keystore (StrongBox where available).
Export audit log
Every export captures a timestamp, destination, and SHA-256 hash of the content. Append-only. Exportable as CSV.
How it works
One device. No round trip.
Everything happens between the microphone and the SQLCipher database on your phone. The only data path out is the export button — and only when you tap it.
1
Record
Tap once. The recorder captures audio at 16 kHz mono to an encrypted file on your device. Pause and resume supported.
2
Transcribe
Whisper runs locally via Dart FFI. The base English model ships in the app. The transcript can build live as you record in an opt-in pull-up sheet, with a post-stop pass as backup. No audio is uploaded — there is nowhere to upload it to.
3
Generate minutes
Gemma 4 E2B runs on-device via LiteRT-LM — an open-weight model you download once over Wi-Fi (~2.6 GB, optional) that works on most Android phones, not just flagships. Every set of minutes leads with a short summary. A deterministic template extractor covers devices that decline the download or are RAM-constrained.
4
Optionally export
PDF, email draft, share sheet, or copy to clipboard. Every export shows a confirmation screen and writes an entry to the local audit log.
Who it's for
People who can't upload the meeting.
SumaFlow Minutes is designed for professionals whose work is governed by confidentiality obligations or principle — and who cannot use cloud meeting tools as a result.
Independent financial advisors
Solo RIAs and registered investment advisors who run 25–80 client meetings a month and cannot use cloud meeting tools because of fiduciary duty and Reg BI obligations. US, UK (FCA), AU (ASIC), and SG advisors alike.
Lawyers, therapists, and journalists
Professionals whose work is confidential by default — privileged conversations, session notes, source interviews. Currently fall back to a yellow pad because cloud AI tools are off-limits.
Technical skeptics
Developers, security professionals, and journalists who will read the architecture page, inspect the manifest, and only adopt tools whose claims they can verify. SumaFlow Minutes is built for them.
Other regulated professionals
Auditors, compliance officers, healthcare and insurance staff, HR teams, and anyone bound by recordkeeping or confidentiality rules that rule out cloud transcription. If a conversation cannot leave the building, it does not have to leave the phone.
SumaFlow Minutes Pro
Power tools for people who live in the app.
SumaFlow Minutes is free to download and stays fully usable for free. Pro adds depth for heavy daily users — on the same on-device, no-cloud architecture.
Why Pro exists
SumaFlow Minutes has no ads, no analytics, no data sale, and no investors monetizing you. Pro is how a tool with clean incentives stays alive. Your records stay on your device whether you pay or not — Pro adds power tools for people who live in the app, and keeps the lights on without compromising the privacy this product is built on.
And there is no lock-in: access to everything you’ve recorded is always free. Pro adds tools — it never locks or paywalls the meetings you already have.

Common questions
Direct answers, no hedging.
Does the app work offline?
Yes. The full record → transcribe → generate minutes flow runs entirely offline. SumaFlow Minutes does not need a network connection to do its job — that is the point.
Do you store my recordings?
No. Audio, transcripts, and minutes stay on your device. There is no server, no account, and no cloud sync. We do not have a copy of your data because there is no place for us to put one.
Can you read my minutes?
No. We cannot read what we never receive. The app does not transmit your audio, transcripts, or minutes to us or to any third party. The core app makes no outbound network calls carrying your content; the one network use is the opt-in AI model download from huggingface.co, which only pulls a public model file down to your device. A privacy regression test enforces huggingface.co as the only allowed host.
Is SumaFlow Minutes HIPAA, FINRA, or SEC compliant?
We do not claim regulatory certifications. The architecture is designed to support your confidentiality obligations under frameworks like Reg BI, FINRA recordkeeping, FCA, ASIC, and similar regimes — but compliance with any specific framework is your responsibility. We recommend reviewing the privacy architecture page with your compliance officer before adoption.
What devices are supported?
Android 10 or newer, ARM64, with at least 4 GB of RAM. On-device AI minutes generation (Gemma 4 E2B via LiteRT-LM) runs on most phones that meet those minimums — no flagship required — after a one-time ~2.6 GB model download over Wi-Fi. If you skip the download or your phone is short on free memory, a deterministic template-based extractor produces useful — if less fluent — minutes instead.
How much does it cost?
SumaFlow Minutes is free to download and stays fully usable for free — the privacy core, your full meeting history, and every export path are always free. SumaFlow Minutes Pro is an optional in-app purchase ($9.99/month, $79/year, or $149 once for lifetime) that adds power tools like higher-quality transcription, custom templates, on-device search, and merge & batch export. Pro is how we keep the lights on with no ads, no analytics, and no data sale.
Is my data uploaded for Pro?
No. Pro runs entirely on-device, exactly like the free app — your audio, transcripts, and minutes never leave your phone. Billing is handled by Google Play, so we never see your payment details, and there is no SumaFlow account or server in the path.
Do I lose my notes if I cancel Pro?
No. Your recordings and minutes are always yours and always free to open — Pro only adds tools, it never locks or paywalls the meetings you already have. If Pro lapses, the power-tool features switch off, but nothing you recorded is taken away.
When can I get it?
Now. SumaFlow Minutes is live on Google Play for Android, free to download. Upgrade to SumaFlow Minutes Pro from inside the app whenever you want the power tools.
Is there an iOS version?
Not yet — Android first. The on-device engines (Whisper via FFI, Gemma 4 E2B via LiteRT-LM) are cross-platform, so the AI path would port directly, but the larger lift is rebuilding the app. iOS is on the v2.0 roadmap.
Does it transcribe while I record?
It can, if you want it to. The recording screen stays calm and minimal by default, but you can pull up a live transcript sheet to watch the text build as you speak. Either way the full transcript is saved when you stop. None of it leaves your phone.
How does the consent prompt work?
Three modes you can configure: Off (records immediately), Verbal capture (plays an editable consent script and records the response as the first segment), or Silent confirm (a modal asks you to confirm you have obtained consent before recording starts). Two-party consent jurisdictions are supported — the in-app guide explains where each applies. This is not legal advice.
Is the code open source?
The privacy-critical modules — recording, encryption, key management, and the network manifest — are open source under a permissive license on the SumaFlow-App GitHub organization. The full app remains a commercial product, but the parts you would want to audit are publicly verifiable.
