Using Sol

  • We give you a personal, non-transferable licence to use Sol on the phones linked to your App Store or Google Play account, under these terms and the store's own rules.
  • Sol has no account. Your photos, videos and recipes are kept on your phone (see our Privacy Policy).
  • You must be old enough where you live to agree to these terms, or have a parent's or guardian's permission.

Free and Sol Pro

  • Free: the full camera, five films, and up to three recipes of your own, with the features listed on our pricing page.
  • Sol Pro: adds every film, unlimited recipes, recipe sharing, and the other Pro features listed on the pricing page. It comes two ways:
    • Monthly: a subscription that renews every month.
    • Annual: a subscription that renews every year.
  • Sol Pro belongs to the store account you bought it with. A subscription from the App Store works on iPhone, and one from Google Play works on Android; they don't carry over between the two.
  • We may add, change or remove features over time. We won't take away the core of what you pay for in Sol Pro without telling you first.

Subscriptions

  • Billing: Sol Pro is bought in the app and billed by Apple through the App Store or by Google through Google Play. The store handles payment, tax and receipts, and its terms apply to the purchase. Prices are shown in the app in your local currency.
  • Auto-renewal: a subscription renews automatically at the end of each month or year, and the store charges you for the next one, until you cancel.
  • Cancelling: cancel in your App Store or Google Play account's subscription settings. On the App Store, cancel at least 24 hours before the renewal date to avoid the next charge. After you cancel, Pro stays on until the end of the period you've paid for. Deleting the app doesn't cancel a subscription.
  • Refunds: refunds are handled by the store under its own policy: Apple at reportaproblem.apple.com, and Google through Google Play. We can't refund store purchases ourselves. If a purchase is refunded, Pro is removed.
  • When a subscription ends: Sol goes back to Free. Your photos, videos and recipes stay on your phone.

Your photos and recipes

What you shoot with Sol, and the recipes you make, are yours. We don't claim any rights in them, and they don't leave your phone unless you send them somewhere. Sol isn't a backup service: keep your own copy of anything you can't afford to lose.

Using Sol fairly

Please don't:

  • copy, resell or redistribute Sol, or get around the Pro checks,
  • reverse engineer the app or this website, except where the law allows it,
  • attack, overload or misuse this website, its launch list or its feedback form,
  • use Sol for anything illegal.

Ownership

Sol, its films, its design, code and name belong to Koji Studios. These terms give you a licence to use Sol; they don't transfer any ownership to you. If you got Sol from the App Store, Apple's standard licence terms also apply.

Updates and availability

We work to keep Sol running well, but we can't promise it will work on every phone or be free of bugs. Updates come through the App Store and Google Play. Some features depend on what your phone's camera can do.

No warranty

Sol is provided "as is". To the extent the law allows, we make no promises beyond those in these terms, including that Sol will fit a particular purpose.

Limitation of liability

To the extent the law allows:

  • we aren't liable for indirect or consequential loss, such as lost profits or lost photos;
  • our total liability to you is limited to the amount you paid for Sol Pro in the 12 months before the claim, or HK$100 if you haven't paid.

Nothing in these terms limits liability that can't be limited by law, or takes away rights you have as a consumer where you live.

Ending

You can stop using Sol at any time by deleting it; cancel any subscription in your store account too. We can end these terms if you break them. The sections on ownership, no warranty, liability and governing law continue after the terms end.

Changes to these terms

If we change these terms in a way that matters, we'll update the date above and say so on the website or in the app before the change takes effect. If you keep using Sol after that, the new terms apply.

Governing law

These terms are governed by the laws of the Hong Kong Special Administrative Region. Any dispute goes to the Hong Kong courts, unless the consumer laws where you live give you the right to bring it locally.
