Privacy Policy

Effective: October 16, 2026Last updated: October 16, 2026

Dynamic Arts, LLC d/b/a Artiol Technology · Baltimore, MD

Artiol Technology is a trading name of Dynamic Arts, LLC, a Maryland limited liability company. In this policy, “we”, “us” and “Artiol” mean Dynamic Arts, LLC.

We handle different products differently, so this policy is split. Part A covers the website (artioltechnology.com), your Artiol account, and the beta portal. Part B covers each app separately, because each one collects different things. We do not sell personal data, and we do not use it for advertising.

Part A

Website and your Artiol account

What we collect

Email addressWhen you create an account, contact us, or apply to the beta programAccount access, transactional email, support replies
Password credentialsAccount creationAuthentication. Passwords are hashed; we never see them in readable form

Cookies

We use essential cookies for authentication and session management. We do not use advertising cookies, and we do not allow third parties to track you across other websites through our site. For aggregate statistics we use Plausible, which is cookieless and collects no personal data.

How your account data is stored

Account data is held in Supabase, with row-level security policies restricting each account’s data to that account. Data is encrypted in transit and at rest. Authentication is handled by Supabase Auth.

Part B

Our applications

Each Artiol app gets its own section. An app collects only what its section says it collects. When we release a new app, we add a section for it before release.

MIDI Sketch

A mobile sketchpad for musicians. Record audio, write chord progressions, sketch in a MIDI piano roll, write guitar tablature, and build rhythms in a step sequencer.

What stays on your device

Your sketches, recordings, chord charts, tablature and rhythm patterns are stored on your device. We do not upload them to our servers, and we cannot see them.

When you choose to export or share a sketch — by email, to another app, or to a file — that content goes wherever you send it. That transfer is at your direction, and the destination’s own privacy policy governs what happens next.

Microphone access

The app asks for microphone permission only when you record. We request it at the moment you tap record, not at launch, and you can decline and still use every other part of the app. Recordings are saved on your device as described above.

What the app sends to us

DataServicePurpose
Feature usage events — which editors you open, which actions you takeGoogle Firebase AnalyticsUnderstanding which parts of the app are used, so we know what to improve
Crash reports and diagnostics — what the app was doing when it stopped working, device model, OS versionGoogle CrashlyticsFinding and fixing bugs
A randomly generated app instance identifierFirebaseDistinguishing one installation from another in the above. Not linked to your name or email
Purchase and subscription statusRevenueCat, Google Play BillingKnowing which features you have access to

We do not receive the contents of your sketches, your recordings, your contacts, your location, or anything you type into a sketch.

Turning analytics off

The app includes a setting to opt out of analytics and diagnostic data collection. You can change it at any time in the app’s settings.

Purchases

Purchases are processed by Google Play. We never see your card number or billing address. Google provides us with a purchase record so we can unlock the features you bought. RevenueCat manages entitlements on our behalf as a service provider.

Age

MIDI Sketch is not directed to children under 13, and we do not knowingly collect personal information from them.

Artiol ID and the Artiol web apps

Artiol ID (id.artiol.app) is one account for the Artiol apps: Lattice, PolyCal, BackPocket, and later CommonPlace.

What Artiol ID keeps

  • Your email and sign-in details.
  • The handle and name you choose.
  • The profile details you add.
  • Your comfort and access settings, which are needs — never conditions or diagnoses.
  • Which apps you have connected and exactly what each may see.
  • The people you have linked with through private invitation links.
  • Who you have blocked.
  • Which apps you have access to.

What it cannot read

Your sealed private details. They are locked with your passphrase (or your device’s fingerprint, face, or key) on your own device before they leave it. We store only the locked copy and cannot open it.

Apps see only what you allow, detail by detail, and you can take any app’s access back at any time in Artiol ID → Keys. An app’s sign-in pass does not carry your email.

Nobody can find you by your email, phone number, name, or handle. People are linked only when one of you sends a private link and the other accepts it.

On your device only

  • Lattice keeps your map on your device. It leaves the device only as a locked copy, and only if you turn that on; we cannot read that copy.
  • Your Lattice health record never leaves your device.
  • BackPocket works without an account.

Deleting your Artiol ID removes your account and what you own in every Artiol app at once. You can also download everything first, as one file, in Artiol ID → Your data.

Backups: deleted information stays in our backups for [backup window — to be confirmed] before it is gone.

Legal requests: we can only ever hand over what our servers can read. Sealed details and Lattice’s locked copies cannot be read by us. [final wording pending legal review]

Who processes data for us

  • Supabase — the database and sign-in.
  • Vercel — hosting.

Neither may use your data for their own purposes.

Google Calendar

Lattice and PolyCal can connect to your Google Calendar if you choose to.

What we access, and only when you turn on the feature that needs it

  • When you are busy (free/busy times), to work out your free time. This is asked for when you press “Connect Google Calendar.”
  • The titles of events on your own calendar, only if you turn on “Show my calendar.”
  • Adding an event to your calendar, only when you confirm that change.

How it is used: only to show your own free time and calendar to you, and, if you choose, the free times you decide to share with people you are linked with. Never for advertising, never sold, never used to train AI models, and never shared with anyone else.

Where it is kept: the access Google gives lasts about an hour and stays in your browser. Your calendar is read in your browser; it is not stored on Artiol’s servers. Free time you choose to share is stored as time ranges only, with no event titles.

Taking it back: press “Disconnect Google Calendar” in the app, or remove Artiol at myaccount.google.com/permissions.

Artiol’s use and transfer of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Beta testing program

If you apply to test a pre-release app, we collect some additional information. This is separate from using a released app.

What we collectWhy
The Google account email used on your Android deviceThis is what Google Play uses to give you access to the test. We cannot enrol you without it
Device model and operating system versionMaking sure we test across real hardware, and interpreting bug reports
Your answers about instruments, software and experienceMatching testers to the right tests and understanding feedback in context
Birth yearConfirming you meet the minimum age for the program
Tasks completed, check-in responses, and bug reports you submitRunning the test and fixing what you find
Your acceptance of the beta tester agreement, and whenKeeping a record of what you agreed to

Your Google account email is shared with Google Play for the sole purpose of enrolling you in the test. We do not use beta program data for marketing. Pre-release builds may collect more diagnostic information than released versions; where that is true, we say so in the app. You can leave the program at any time by telling us, and we will remove you and delete your program data on request.

How we use your information

We use what we collect to:

  • Give you access to your account and the features you have paid for
  • Deliver and support our products
  • Fix bugs and crashes
  • Understand which features are used, so we know what to build and improve
  • Send transactional messages: receipts, password resets, beta instructions, and policy-change notices
  • Run the beta testing program and meet our legal obligations

What we do not do

  • We do not sell your personal data, under any definition, including the broad definitions in California and other US state privacy laws
  • We do not share your data with advertisers or data brokers
  • We do not use your creative work to train machine learning models
  • We do not track you across other apps or websites
  • We do not send marketing email unless you ask us to

The third point deserves saying plainly: the music you make in our apps is yours. We do not claim rights in it, and we do not feed it into anything.

Third-party services

These companies process data on our behalf, or receive data when you choose to send it. Each has its own privacy policy.

ServiceWhat it doesWhere it applies
SupabaseDatabase and authenticationWebsite and account
VercelWebsite hostingWebsite
ResendTransactional emailWebsite and beta program
PlausibleCookieless website analyticsWebsite
Google FirebaseAnalytics and crash reportingAndroid apps (MIDI Sketch)
Google PlayApp distribution, in-app purchases, beta enrolmentAndroid apps and beta program
RevenueCatManaging purchase entitlementsAndroid apps with in-app purchases

Artiol ID, Lattice, PolyCal, and BackPocket on the web use no analytics, no crash reporting services, and no third-party scripts.

We choose providers who process data for us under contract, as service providers, rather than for their own purposes. Adding a new provider that handles personal data means updating this table before it goes live.

How long we keep things

DataRetention
Account dataFor as long as your account is open, then deleted within 30 days of your deletion request
Analytics and crash dataUp to 14 months, then deleted automatically
Beta program dataFor the duration of the program plus 6 months, then deleted
Support and contact messages2 years
Purchase records7 years, because tax and accounting rules require it
Content you created in an appStored on your device, under your control. Deleting the app deletes it

Purchase records are the one category we cannot delete on request before the retention period ends. Everything else goes.

Your rights

You can ask us to:

  • Show you what personal data we hold about you
  • Correct anything that is wrong
  • Delete your account and your data
  • Export a copy of your data in a portable format
  • Stop or restrict how we process your data
  • Opt out of analytics, through the setting in the app

We will not treat you differently for exercising any of these.

Deleting your account

You can request deletion of your account and associated data at artioltechnology.com/delete-account. That page works whether or not you still have an app installed, and whether or not you can sign in. If you have an Artiol website or beta-portal account, you can also delete it from your account settings. The MIDI Sketch app does not create an account; uninstalling it removes the content stored on your device, and you can use the deletion page to request removal of any remaining data tied to your use of the app (such as analytics identifiers), subject to the retention periods above. When you delete your account we remove your profile, your beta program records, and your analytics identifiers. Purchase records are retained as described above. Deletion is completed within 30 days.

State privacy rights

Residents of California, Colorado, Connecticut, Virginia and other US states with comprehensive privacy laws have the rights listed above. We do not sell or share personal information as those terms are defined, and we do not process it for targeted advertising or profiling. To exercise any right, email admin@dynamic-arts.net. We respond within 30 days and ask only for what is necessary to verify your identity.

Children

Our products are not directed to children under 13, and we do not knowingly collect personal information from them. If we learn that we have, we delete it. If you believe a child has given us personal information, email admin@dynamic-arts.net and we will remove it.

Security

We encrypt data in transit and at rest, restrict access to the people who need it, and use row-level security so one account cannot reach another’s data. No system is perfectly secure, and we will not claim otherwise. If a breach affects your personal data, we will notify you and the relevant authorities as the law requires.

Where your data is held

We are based in the United States and our providers process data in the United States. If you use our products from outside the US, your data is transferred there. We rely on standard contractual protections with our providers for those transfers.

Changes to this policy

We update this policy when our products change. For changes that materially affect how we handle your data, we give notice before they take effect — by email to registered users, and in the app where it applies. Continuing to use our products after that date means the updated policy applies.
