Terms of Use

These terms apply to GRKU (the software for the SD card), to grku.app (the site), and to GRKU Plus (the paid part of the site). When you install GRKU, use the site, or buy GRKU Plus, you accept these terms. If you do not accept them, do not install GRKU and do not buy GRKU Plus.

GRKU is made by BOTNICK, Thailand, referred to as "we" below. To contact us, use the feedback link on https://grku.app.

Experimental software

GRKU is free, open-source software under the MIT License. The effects have their own licenses. GRKU is experimental. Ricoh does not make, support, or endorse GRKU.

GRKU runs from the SD card. It changes the camera only until the camera turns off, and it does not write the firmware. The installation turns on the SD script setting of the camera. This setting stays on until you turn it off. GRKU never ships or asks for a modified firmware.

Risks

• If GRKU fails, the camera can stop during startup. The recovery guide tells you how to start the camera again. Read it before you install.
• On a camera or a firmware version that was not tested, GRKU can fail or work incorrectly. GRKU's own changes have run on a GR IV with firmware 1.11; other cameras and versions are built from the same code but may not have been run on a camera.
• Ricoh may decline warranty or repair service for a camera that used third-party software.
• Before you install or update GRKU, copy your photos from the SD card.
• The previews on the site are approximations. Photos from the camera can look different.

GRKU Plus

GRKU Plus is a one-time purchase that unlocks more film looks on the site: more slots on the card, one pack of looks, or every look. What is free stays free: the site previews every look, and ten looks of your choice, every module, recipes, and the film library file are free.

What you buy

• You buy a licence to use the unlocked looks with GRKU on your own cameras. The looks remain under their own open licences; the purchase pays for the service and the work, not for the look files.
• The purchase is delivered as a key, sent to the email you give and shown on the page. The key works on every device where you open the site. Keep it like a password: anyone who has it can use it.
• A key is bound to the email that bought it. "Everything" includes every look that exists at the time of purchase and every look added later, for as long as the site runs.

Prices and payment

• Prices are in Thai baht and are shown on the site before you pay. They can change; a change does not affect a purchase already made.
• Payment is by PromptPay transfer to the account shown on the payment card, or by a TrueMoney Wallet gift link, as the site offers at the time. We do not take card numbers and never ask for your banking password.
• The QR of an order carries the exact amount and is valid for the time shown. Pay exactly the amount of your order; the slip must match the amount, the receiving account, and the time of the order.
• The payment card is issued for you and carries your email, the order number, and the time. Do not forward it; a payment made with a forwarded card goes to the order of the person it was issued to.
• Banks settle around midnight; a transfer between 23:00 and 00:10 can produce a slip that is read late. Prefer another time, or wait and upload the slip later: the order stays open for the time shown.

Verification and delivery

• You upload the slip from your bank app. We read it through a slip verification service (EasySlip Co., Ltd., Thailand), which checks the transfer with the bank network. A slip that cannot be read, does not match the order, was used before, or paid someone else is declined, and the order stays open for a correct slip.
• A TrueMoney Wallet gift link is redeemed to our wallet when you submit it. A gift of at least the order's amount pays the order. A smaller gift is kept as credit on your order and the order asks for the rest; a larger gift pays the order and the excess is kept as credit on your email toward a later purchase. A gift link cannot be given back once redeemed, because TrueMoney does not allow it.
• Delivery is immediate on a verified payment: the page unlocks and the key is sent to your email. If the email does not arrive within an hour, use "I have a key" on the site to have it sent again, or contact us with the order number.

Refunds

• A purchase is a digital licence delivered at once. Thai law lets us decline a refund for change of mind after delivery, and we do.
• We refund in full when we cannot deliver: the key does not arrive and we cannot provide it, or the unlocked looks do not work on the site for your account because of an error on our side that we cannot fix within fourteen days of your report.
• We do not refund because GRKU does not work on a particular camera or firmware, because a look does not look as you expected, or because you no longer own the camera. GRKU is experimental and free, and GRKU Plus unlocks looks on the site; it does not sell camera functionality.
• A refund goes back by PromptPay to the account that paid, within fourteen days of our decision.

Fair use and misuse

• A key is for you and your cameras. Do not sell, share, or publish keys, slips, or payment cards. We may deactivate a key that is shared publicly or used to defraud, after notice to the email of the purchase where we can give notice.
• Forged or altered slips, slips of transfers to other people, and attempts to redeem one payment twice are fraud. We decline them and may refuse further orders from the same email or device. Where the law requires, we report them.
• We may refuse an order before payment, for any reason, and we tell you so on the page.

Personal data

• To sell GRKU Plus we process: your email (to send and bind the key), the order (tier, amount, time), the slip image you upload (sent to the verification service, not kept by us beyond the verification), the transfer reference, the sender name as the slip shows it, and the amount. For a TrueMoney gift, the gift link and the name of the giver as TrueMoney returns it.
• We use this data to deliver the purchase, to prevent fraud, and to keep the accounts the law requires. We keep orders and references for five years for tax and accounting; we do not use your email for marketing and we do not sell data.
• The verification service and our hosting provider (Cloudflare, Inc.) process data on our behalf under their own terms. The slip you upload passes through them.
• You may ask what we hold about your email, ask for a correction, or ask for deletion of what the law does not require us to keep, by contacting us. This section is our notice under the Personal Data Protection Act B.E. 2562.

The service

• GRKU Plus is a service of the site. We aim to keep it running, but we do not promise that it is available at every moment, and we may change how it works. If we stop the service, keys issued before keep working for the looks that exist on the site at that time, as long as the site runs, and the site stays online for at least twelve months after the announcement.
• The free part of GRKU does not depend on the service: the software, the modules, and the library file stay available under their open licences.

No warranty

GRKU and grku.app are provided "as is", without warranty of any kind. We do not promise that GRKU works on your camera, that it has no errors, or that photos look as the preview shows. GRKU Plus is sold as described in these terms; nothing more is promised.

Limitation of liability

You use GRKU at your own risk. To the maximum extent that the applicable law permits, we are not liable for damage to the camera or the SD card, for lost photos or data, or for other loss that comes from the use of GRKU, of grku.app, or of GRKU Plus. For GRKU Plus, our liability to you is limited to the amount you paid for the purchase in question. These terms do not exclude a liability that the applicable law does not permit to exclude, and they do not limit the rights that Thai consumer protection law gives you and that cannot be waived.

Trademarks and affiliation

GRKU is an independent project. It is not affiliated with or endorsed by Ricoh Company, Ltd., PromptPay, TrueMoney, EasySlip, or any bank, and not by Kodak, Fujifilm, Ilford, or any other maker of film. Camera, film, and payment names are trademarks of their owners and are used only to say what GRKU works with.

Governing law

These terms are governed by the law of Thailand. A dispute goes to the competent court in Thailand, without prejudice to the rights a consumer has to bring a case where they live. If a part of these terms is invalid, the rest stays in force.

Changes

These terms can change. The current terms are on this page, with the date of the last change in the history of this file. A purchase is governed by the terms shown when it was made, except where the law requires otherwise. If a translation differs from the English text, the English text applies.
