SleepHQ Alternative: Why CPAP Clarity Is Free, Private, and Instant

What Is SleepHQ?

SleepHQ is a web-based CPAP data analysis platform that launched as a modern alternative to desktop tools like OSCAR. It lets you upload your SD card data to the cloud, view charts and metrics in your browser, and track your therapy over time. The platform supports multiple CPAP brands and has built a community of users who share insights and compare notes.

SleepHQ offers two tiers. The free tier gives you basic data viewing with limited history. The Pro tier costs $15 per month or $120 per year (pricing as of March 2026) and unlocks full history, advanced charts, data exports, and priority support. They also sell a dedicated SD card uploader device that automatically syncs your data to the cloud each morning, so you never have to remove your card manually.

It is a well-built product with a loyal user base. But there are two things worth thinking about before you sign up: where your health data goes, and what it costs you.

The Privacy Question

When you upload your CPAP data to SleepHQ, your health information leaves your device and lives on someone else's servers. Your nightly breathing events, apnea counts, leak rates, therapy pressures, and usage hours are all stored in the cloud. SleepHQ processes this data, indexes it, and keeps it available for you to access through their platform.

For some people, that is perfectly fine. Cloud storage is convenient, and SleepHQ has a privacy policy outlining how they handle your data.

But CPAP data is health data. It reveals intimate details about your body while you sleep. In the United States, CPAP data uploaded to a third-party web app is generally not protected by HIPAA the way data at your doctor's office would be. Once it is on someone else's server, you are trusting their security practices, their business decisions, and their long-term viability as a company.

CPAP Clarity takes a fundamentally different approach. All data processing happens entirely in your browser using JavaScript. Your SD card files are read locally, parsed locally, and displayed locally. Nothing is uploaded. There is no server-side processing, no cloud storage, no account, and no way for us to access your health data, because we never receive it. If you close the tab, you can also clear your local data with a single click.

This is not a marketing angle. It is an architectural decision baked into the code. There is no upload endpoint on our server because none was ever built.

The free tier of SleepHQ is quite limited. The seven-day history window means you cannot track trends over weeks or months without upgrading. Most of the features that make SleepHQ useful are locked behind the Pro subscription. CPAP Clarity offers its full feature set with no paywall, no time limits, and no account creation.

What CPAP Clarity Does Better

It is free, and stays free. No subscription tiers, no feature gating, no "upgrade to unlock" prompts. Every chart, every insight, every PDF report is available to every user. The project is supported by contextual affiliate links to CPAP supplies, not by charging you for access to your own health data.

Your data never leaves your device. This is the core difference. CPAP Clarity processes everything client-side. Your browser does the work. If privacy matters to you, and with health data it should, this is a meaningful distinction.

It works instantly. There is no account to create, no email to verify, no password to remember. You open the page, drop in your SD card folder, and see your results. The whole process takes under a minute. Read our complete guide for a walkthrough, or see how to import from your phone if you prefer mobile.

Smart insights in plain English. CPAP Clarity does not just show you numbers. It tells you what they mean. If your leak rate is elevated, you will see a specific recommendation about mask fit. If your events are mostly central rather than obstructive, you will see an explanation of what that means for your therapy. These insights are prioritized by clinical importance, so the most actionable items appear first.

Therapy Score and Recovery Index. The history view calculates a composite therapy score from 0 to 100 that weighs AHI control, usage hours, mask seal quality, and nightly consistency. This gives you a single number to track week over week, making it easy to spot whether your therapy is trending in the right direction.

PDF reports for your doctor. Both single-night and multi-night summary reports can be downloaded as PDFs, formatted for clinical review. Bring them to your next sleep doctor appointment instead of trying to remember how last month went.

What SleepHQ Does Better

Being fair matters. SleepHQ has real strengths that CPAP Clarity does not match today.

Wider device support. SleepHQ works with ResMed, Philips Respironics, Fisher & Paykel, and other CPAP brands. CPAP Clarity currently supports ResMed AirSense 10 and AirSense 11 only. If you use a different machine, SleepHQ is one of your best options.

Cloud sync and access from anywhere. Because your data lives on their servers, you can access it from any device without re-importing. If you check your data from multiple computers or share access with a family member, cloud storage is genuinely convenient. CPAP Clarity stores data in your browser's local storage, which means it is tied to that specific browser on that specific device.

Auto-upload hardware. SleepHQ sells a small device that reads your SD card automatically and uploads data to your account. If you want a truly hands-off workflow where you never touch your SD card, this is a real convenience that local-only tools cannot replicate.

Community and forums. SleepHQ has an active user community where people discuss their data, share tips, and help each other troubleshoot. If you value peer support and learning from other CPAP users, that community has genuine value. Apneaboard.com serves a similar role for OSCAR users.

Who Should Use Which?

Choose CPAP Clarity if:

• You use a ResMed AirSense 10 or 11
• Privacy matters to you and you prefer your health data to stay on your device
• You do not want to pay $15 per month (as of March 2026) for CPAP analytics
• You want plain-English insights, not just raw charts
• You need PDF reports for your doctor
• You want to start analyzing your data right now, with zero setup

Choose SleepHQ if:

• You use a non-ResMed machine (Philips, Fisher & Paykel, etc.)
• You need cloud access from multiple devices
• You want the auto-upload hardware for a hands-off workflow
• Community interaction and peer support are important to you

Use both if you want the convenience of SleepHQ's cloud sync for passive tracking and CPAP Clarity's privacy-first analysis for deeper insights and doctor reports. They are not mutually exclusive.

See for Yourself

The best way to compare is to try it. CPAP Clarity takes under a minute to get started, and you do not need to enter an email, create a password, or hand over any personal information.

If you have a ResMed AirSense 11 (opens in new tab) or AirSense 10, pull your SD card, open cpapclarity.com, and drop in your DATALOG folder. If you do not have your SD card handy, click "Try with sample data" on the homepage to explore the full dashboard with realistic demo data.

Your therapy data belongs to you. Understanding it should not require a paid subscription.
