License Types

The public types backing Octet.start(...) and OctetSdk.licenseStatus. See License & Activation for the timeline model.

LicenseStatus

Snapshot of the SDK's current license state. Read synchronously from OctetSdk.licenseStatus.

public struct LicenseStatus: Sendable, Equatable {
    public let state: LicenseState
    public let activatedAt: Date?
    public let hardStopAt: Date?
    public let daysUntilHardStop: Int?
    public let tier: String
    public let upgradeRecommended: Bool       // soft version hint; false until backend gating is on
    public let minSupportedVersion: String?   // soft version hint; nil until backend gating is on
}
data class LicenseStatus(
    val state: LicenseState,
    val activatedAt: Instant?,
    val hardStopAt: Instant?,
    val daysUntilHardStop: Int?,
    val tier: String,
    val upgradeRecommended: Boolean,      // soft version hint; false until backend gating is on
    val minSupportedVersion: String?,     // soft version hint; null until backend gating is on
)
Field Meaning
state Coarse state that drives in-app UI. See LicenseState below.
activatedAt First successful activation timestamp. nil pre-activation, or in INVALID.
hardStopAt The license's exp. Octet maintains active licenses, so this value advances as the license renews. Do not design around a fixed cutoff. Identical for every device that activates this license.
daysUntilHardStop ceil((hardStopAt - now) / 1 day). Useful for "X days left" banners.
tier Tier carried in the license token.
upgradeRecommended Soft version hint, added in 1.2. true when the backend reports this SDK version as behind the recommended floor. false until backend version gating is enabled.
minSupportedVersion Soft version hint, added in 1.2. The lowest SDK version the backend supports, or nil/null until gating is enabled. Pair it with upgradeRecommended to prompt an in-app update.

Android: in 3.0, LicenseStatus gained three trailing constructor parameters for Octet's internal use, each with a default. Source that calls its constructor or copy compiles unchanged, with positional or named arguments. Code compiled against 2.0.0 that calls the constructor or copy must be recompiled.

LicenseState

Octet maintains active licenses, so a license in normal use stays in ACTIVE. RENEWAL_RECOMMENDED, GRACE_PERIOD, EXPIRED and REVOKED cover prolonged-offline and revocation handling, not an age-based trial clock.

public enum LicenseState: String, Sendable {
    case notActivated       = "NOT_ACTIVATED"
    case active             = "ACTIVE"
    case renewalRecommended = "RENEWAL_RECOMMENDED"
    case gracePeriod        = "GRACE_PERIOD"
    case expired            = "EXPIRED"
    case revoked            = "REVOKED"
    case invalid            = "INVALID"
}
enum class LicenseState {
    NOT_ACTIVATED,
    ACTIVE,
    RENEWAL_RECOMMENDED,
    GRACE_PERIOD,
    EXPIRED,
    REVOKED,
    INVALID,
}
State Meaning
NOT_ACTIVATED License verified, never activated.
ACTIVE Activated and current. The normal steady state for a maintained license.
RENEWAL_RECOMMENDED Activated, nearing the license exp. Maintained licenses renew automatically. Surface a banner only if you want to.
GRACE_PERIOD Cached activation past its exp but within the offline tolerance. The device could not reach the backend to refresh. SDK keeps working.
EXPIRED Cached activation past the offline tolerance with no backend reachable to refresh. SDK refused to start. Age alone no longer expires a maintained license. Since 3.1, also a license that expired while the session was running: predicates return INDETERMINATE with reason LICENSE_INACTIVE.
REVOKED Added in 3.1. Octet withdrew the license while the session was running. Predicates return INDETERMINATE with reason LICENSE_INACTIVE and make no proof, and the next Octet.start throws a LicenseError.
INVALID Signature failed, server rejected, or malformed. SDK refused to start.
Caution

LicenseState drives in-app UI only. The activation token enforces the cryptographic gate, so a forged state = ACTIVE has no effect on it.

LicenseError

Thrown by Octet.start(...) for every license-related failure. The SDK guarantees one of these subtypes. It never throws a raw Error / Exception for license reasons.

public enum LicenseError: Error, Sendable, Equatable {
    case malformedKey
    case noActivation
    case expired
    case activationWindowClosed
    case revoked
    case network(message: String)
    case serverRejected(httpStatus: Int, reason: String)
    case upgradeRequired(minVersion: String, message: String)
    case bootstrapFailed(reason: BootstrapReason)
}
sealed class LicenseError(message: String) : Exception(message) {
    object MalformedKey            : LicenseError(...)
    object NoActivation            : LicenseError(...)
    object Expired                 : LicenseError(...)
    object ActivationWindowClosed  : LicenseError(...)
    object Revoked                 : LicenseError(...)
    data class Network(override val cause: Throwable) : LicenseError(...)
    data class ServerRejected(val httpStatus: Int, val reason: String) : LicenseError(...)
    data class UpgradeRequired(val minVersion: String, val message: String) : LicenseError(...)
    data class BootstrapFailed(
        val reason: BootstrapReason,
        val upgradeUrl: String? = null,   // set for NewDevicesBlocked
    ) : LicenseError(...)
}
Case When Fix
MalformedKey Local PASETO signature or structural failure on the license token the SDK obtained through attested bootstrap. Confirm the SDK is a supported version. Contact support if it persists.
NoActivation No cached activation, and offline (the SDK can't reach the license backend to bootstrap). Retry when network returns.
Expired Cached activation past the offline grace with the backend unreachable to refresh. Reconnect so the SDK can re-activate.
ActivationWindowClosed Server returned 403 activation_window_closed. Not returned under the current maintained-license model. Retained for compatibility. Contact support.
Revoked Server returned 403 revoked (admin revoke). Contact support.
Network Transient network failure during activation. message (iOS) or cause (Android) carries the underlying error for diagnostics. Retry. Do not parse the message for control flow.
ServerRejected Any other HTTP rejection (app_blocked, ip_blocked, …). Inspect reason.
UpgradeRequired Backend rejected this SDK version as out of support (version gating, added in 1.2). Update the SDK to minVersion or later.
BootstrapFailed Attested bootstrap failed. reason carries a BootstrapReason. Added in 2.0. See the BootstrapReason table below.

BootstrapReason

Carried by bootstrapFailed. Each case except sandboxNotPermitted maps to a typed detail code the license backend returns for POST /v1/bootstrap, identically on both platforms. sandboxNotPermitted is raised by the SDK before any request is sent. See Attested bootstrap.

Reason Meaning
attestationInvalid The App Attest object / key-attestation chain did not verify against the platform root.
appNotRegistered The app identity is not registered to any account.
appDisputed The app identity is contested and not yet resolved.
accountDisabled The owning account is disabled.
bootstrapReplay The bootstrap challenge was already used, or was not one the server issued.
deviceLimitReached The license's device cap, set by Octet, is reached. Licenses have no cap by default. Devices that already activated are unaffected.
newDevicesBlocked Added in 3.0. The account accepts no new devices. Devices that already activated are unaffected. The error carries a server-signed upgrade link, upgradeUrl.
appPendingContested Added in 3.1. Another license claims the same app, and your pending registration lost that claim. Register the app again, or contact Octet support.
pendingRateLimit A newly registered app is still rate-limited.
seedInvalid The runtime seed (web / desktop channel) did not verify.
sandboxTokenInvalid The sandbox bypass token did not verify.
sandboxNotPermitted A sandbox token was presented from a store build. Raised locally by the SDK, never sent.

Handling newDevicesBlocked

Send the user to upgradeUrl. The link is server-signed, so open it exactly as received and never build one yourself. On iOS the link is the case's associated value, .newDevicesBlocked(upgradeUrl:). On Android it is LicenseError.BootstrapFailed.upgradeUrl, set when reason is BootstrapReason.NewDevicesBlocked. The value is nil / null only if the server sent no link.

On Android, a when (reason) over BootstrapReason without an else branch no longer compiles against 3.0 or 3.1. Add the new cases or an else branch.

do {
    let sdk = try await Octet.start(config: config)
} catch LicenseError.bootstrapFailed(reason: .newDevicesBlocked(let upgradeUrl)) {
    if let link = upgradeUrl, let url = URL(string: link) {
        await UIApplication.shared.open(url)   // open exactly as received
    }
}
try {
    val sdk = Octet.start(context = applicationContext, config = config)
} catch (e: LicenseError.BootstrapFailed) {
    when (e.reason) {
        BootstrapReason.NewDevicesBlocked ->
            e.upgradeUrl?.let { startActivity(Intent(Intent.ACTION_VIEW, Uri.parse(it))) }
        else -> showStartupError(e)
    }
}

Reading the status at runtime

guard let status = sdk.licenseStatus else { return }
switch status.state {
case .renewalRecommended:
    break  // maintained licenses renew automatically
case .gracePeriod:
    showBanner("Connect to the internet to refresh the license")
case .expired, .revoked, .invalid:
    showBlocker()
case .active, .notActivated:
    break  // happy path
}
val status = sdk.licenseStatus ?: return
when (status.state) {
    LicenseState.RENEWAL_RECOMMENDED -> { /* maintained licenses renew automatically */ }
    LicenseState.GRACE_PERIOD ->
        showBanner("Connect to the internet to refresh the license")
    LicenseState.EXPIRED, LicenseState.REVOKED, LicenseState.INVALID ->
        showBlocker()
    LicenseState.ACTIVE, LicenseState.NOT_ACTIVATED -> {
        // happy path
    }
}
