Privacy Policy

Effective August 31, 2026

The short version: your practice stays on your device. Strumhold has no ads, no analytics scripts, and we never sell data. The only personal data we ask you for is what a paid account needs. Like every website, Strumhold is delivered by a host that sees ordinary web requests, and this page explains exactly what that means and what we keep.

What stays on your device

Everything the free app does happens locally: your practice history, your drill recordings, and your settings are stored in your browser on your device. None of it ever leaves. If you never create an account, we have no idea who you are and nothing that could tell us.

The app does talk to our server, and we would rather explain it than let you find it. When you open Strumhold it asks two questions: what its own settings are, and whether this browser is signed in. It has to ask the second one, because the sign-in cookie is deliberately hidden from the app's own code, so asking the server is the only way to know. Neither question sends anything about you or your practice. Nothing you play is ever part of it.

Our host is Cloudflare, and like any web host it receives the requests your browser makes, including your IP address and which browser you use. Their dashboard shows us summaries of that for about a day, and the detailed records behind it stay available to us for about a week. We don't use any of it to identify anyone, we have no way to connect it to anything you practise, and the only things we ever copy out of it are the daily tallies described in How we count visitors below. After that week the detailed records are gone from their systems too; what stays there for about a year are whole-day totals, such as requests per country, with nothing about any individual request in them.

Your microphone

Strumhold asks for microphone access to score your playing. The audio is processed on your device, as you play, and is never uploaded. When a drill finishes, the app keeps a recording of it so you can listen back to your own playing and check a score you disagree with. That happens for every drill, without you asking for it. Each recording is stored on that device only, it is never uploaded and never synced between your devices, and older ones are deleted automatically unless you pin them. Note that browsers label every audio input a “microphone”. If you play through an audio interface or line-in, the same permission covers it, and the audio is handled the same way: on your device, never uploaded.

If you are weighing this up against other apps, we read what five guitar practice apps publish about the audio they hear, quoted it, and linked every source: guitar practice apps and your microphone.

If you create an account

Accounts exist only for the paid subscriptions, and you sign in with Google. From Google we receive and store your email address and whether Google has verified it. We may occasionally use it to contact you about your account or to ask for feedback, never marketing, and we never share it. Reply to any such email and we’ll stop. We use an essential session cookie to keep you signed in, and no cookies for tracking.

If you subscribe

Stripe sells and bills the subscriptions through its Link checkout, as the merchant of record rather than as our payment processor. Your card details go to Stripe, never to us, and Stripe holds that payment data as its own under its privacy policy. All we store is your subscription status and a Stripe customer reference, so the app knows what you are subscribed to.

Deleting your payment data with Stripe does not delete your Strumhold account. If you ask Stripe or Link to erase your payment details, the subscription stops and switches off. To us that looks exactly like any other cancellation, so your email address and your backed-up practice history stay with us and are kept for the 12 months described below. We'd rather keep your backup for a year than destroy it because of a billing signal you may not have meant that way. To delete the Strumhold account and its server-side data, email support@strumhold.com from the address you signed in with.

What Sync stores on our servers

Sync's whole job is to back up your practice history and copy it between your devices, so while you're subscribed we store that history (your drills and practice events, not audio) on our servers, hosted on Cloudflare's infrastructure. If your subscription ends, we keep that backup for 12 months, so you can pick sync back up without losing anything, and then delete it. Your local copy is unaffected.

What we don't do

How we count visitors

We'd like to know whether anybody is finding Strumhold, and where from. Here is everything we record about visits. It is more than this page used to describe: at first we only counted pages, and we now also count countries, because we want to know which of our efforts bring people here.

Once a day, we ask our host two questions about yesterday, and write the answers down. How many requests did each page address get, and how many of those failed? How many requests came from each country? Every record is a date, one name (a page address or a country), and a number. That's the entire database, and it's kept forever because there's nothing in it worth deleting.

The two answers are stored apart and never combined. We can see that some visits came from France and that some pages were popular, but nothing we keep can say which pages the visits from France went to; the code refuses to ask that question. And these are counts of requests, not of people: one person visiting ten times and ten people visiting once look exactly the same to us.

Our country numbers reach back about a year further than the rest, because our host keeps whole-day country totals for about that long and we copied them when we started counting. Same shape: a date, a country, and a number.

There is no analytics script, on the app or on this site. Nothing is written to your device and nothing is read from it. No cookies, no fingerprinting, no identifier of any kind, not even an anonymous one. Your browser doesn't send us anything extra, because we didn't add anything for it to send. We're just keeping our own copies of numbers our host already shows us, before their records of them expire.

What that means in practice: we can see how many times the app was opened yesterday and which countries yesterday's visits came from. We can't see whether you were one of them, or whether all of them were the same person.

There's a trade-off in that, and it's worth being straight about: because we don't watch what you do in the app, we're partly blind. We can't see which drills people get stuck on, what's confusing, or what quietly broke. So please tell us. If something annoys you, doesn't work, or you wish it worked differently, write to support@strumhold.com. That's genuinely our main way of finding out, and we'd rather hear it from you than take it from your device.

Your choices

You can export your practice history from the app at any time, and cancel Sync self-service via Manage subscription. To delete your account and its server-side data, email support@strumhold.com from the address you signed in with.
