All traffic between respondents, field devices, and our servers is encrypted over TLS/HTTPS. There is no unencrypted path into the platform.
Audio recordings and transcripts are stored in access-controlled object storage and a managed database, both encrypted at rest by our infrastructure provider.
VoiceInsights Africa runs on Cloudflare's global edge network (Workers, D1, R2) — the same class of infrastructure used by major global platforms — with Twilio for telephony and messaging delivery.
Every account has a defined role — organization admin, M&E officer, or system administrator — that scopes exactly what data they can see and act on.
Passwords are hashed with PBKDF2 and never stored in plain text. Sessions use signed, time-limited tokens.
Automated checks flag near-duplicate responses and suspicious submission speed on every incoming answer, across every channel.
VoiceInsights Africa Ltd is registered with the Personal Data Protection Commission (PDPC) of Tanzania as a Data Controller, under the Personal Data Protection Act, No. 11 of 2022 — the law that governs how personal data is collected, processed, and protected in Tanzania. This is in addition to designing our systems in line with globally recognized principles such as GDPR.
Registered with Tanzania's PDPC as required by law.
Consent obtained before every interview, on every channel.
We collect only what's necessary for your research purpose.
Data residency handled in line with PDPA restrictions on transfers outside Tanzania.
Every response, transcript, and report generated through your account belongs to your organization. VoiceInsights Africa processes it on your behalf and never sells or shares client data with third parties.
Response data is stored on Cloudflare D1, which maintains automatic point-in-time recovery — your data isn't a single point of failure.
Voice recordings are stored on Cloudflare R2, built for eleven-nines (99.999999999%) durability with redundancy across multiple facilities.
The platform runs on Cloudflare's global network, not a single server — a regional outage in one location doesn't take the whole platform down.
Security-relevant events (logins, invites, permission changes) are logged to an audit trail your Org Admin can review at any time.
This describes the resilience built into our current infrastructure. A formal, independently-audited disaster recovery runbook with tested Recovery Time/Point Objectives (RTO/RPO) is on our roadmap as we take on larger enterprise and government contracts — ask us for the current status if this is a procurement requirement for your organization.
Many platforms advertise a single headline accuracy percentage. We think that's misleading — accuracy varies by audio quality, background noise, dialect, and channel. Instead, here's exactly how VoiceInsights Africa computes the numbers your own dashboard shows:
Computed directly from OpenAI Whisper's own per-segment log-probability output for every single voice response — not a marketing estimate. You see the real average for your own data in Model Performance.
Flags are based on measurable signals — response speed, duplicate phrasing, answer-length anomalies — each visible per-flag in Fraud Alerts, not a black-box score.
Sentiment and key findings are generated by Claude Sonnet 5 grounded in your own verbatim transcripts — every finding is checked against real data, not templated.
Every client sees their own real, current operational stats in-app (Model Performance) — updated live, not a static claim on a website.
We don't yet have enough aggregated production volume across enough clients to publish a statistically meaningful platform-wide benchmark — and we'd rather say that plainly than publish an inflated number. Check our live status page for current platform health.
We're happy to complete vendor security assessments and NDAs for procurement processes.
