Mail-in repair terms (郵送修理規約)

Please read these terms before you apply for a mail-in repair. By applying, you are treated as having agreed to them.

Application and sending

Application Apply with the online form or the application form (PDF). Send the device only after we have contacted you to say "please send it". We may not be able to accept a device that arrives before we contact you.
How to send Send it by Yu-Pack (ゆうパック, Japan Post) or Takkyubin (宅急便, Yamato Transport), which have tracking and compensation, with the shipping paid by you (元払い, sender pays). We cannot accept Letter Pack (レターパック), non-standard-size mail (定形外郵便), ordinary mail (普通郵便), mail-delivery services (メール便) or recipient pays (着払い). In the item description field (品名欄), write 「スマートフォン（リチウムイオン電池内蔵）」 (it means "smartphone (built-in lithium-ion battery)").
Do not enclose Remove the SIM card, SD card, case, charger and cable, and keep them with you.
Swollen batteries It may not be possible to transport a device with a swollen battery. Do not mail it; please bring it to the shop.
Accidents in transit Loss or damage in transit from you to our shop is covered by the carrier’s compensation system. Before sending, take photos of the device and keep your copy of the shipping label. For accidents while we return the device to you, we deal with the carrier.
Check on arrival We record the opening of the package on video and check the appearance and operation of the device.

Quote The prices shown on the website are estimates. If the diagnosis after arrival changes the work or the amount, we will always contact you, and we start work only after you approve.
If you decline the repair If you decline the repair after the quote, we charge a diagnostic fee of ¥2,500–¥5,000, depending on the materials used and the difficulty of the work, plus the return shipping fee.
Water-damaged or heavily impacted devices We will try to repair the device so that it can be used again. Even if it cannot be made usable, if we are able to recover the data in some way, we charge the logic board repair fee.
Long repairs If the repair is expected to take one week or more, for example because parts are hard to get or the cause of the fault cannot be identified, we may return the device unrepaired. In this case there is no diagnostic fee (you pay the return shipping fee).
Shipping costs You pay the shipping to our shop. You also pay the return shipping (Yu-Pack) and the cash on delivery (代金引換) fee, but if the repair total (tax included) is ¥10,000 or more, we pay them.
Payment Pay by cash on delivery (Yu-Pack, cash) or by bank transfer before the return. You pay the bank transfer fee.

Opening the device Because of the manufacturer’s design, some devices are hard to open, for example because of strong adhesive or press-fitted parts. Even when we work carefully with special tools, small marks may in rare cases remain on the body.
Parts We choose and use the best parts available on the market. They are not genuine manufacturer parts, so their color or size may differ slightly from the original parts.
Messages after a part replacement The serial number of a replacement part does not match the original number registered in the device, so an error or notification may appear. We are not an authorized service provider of the manufacturer, so you may no longer be able to receive the manufacturer’s warranty (such as AppleCare).
Water resistance After a repair, the device’s water resistance is reduced. On request, we can fit a dust- and water-resistant gasket for an extra charge. However, this does not guarantee water resistance.

Passcode We ask for the passcode only in the dedicated field of the online form, or by phone after the device arrives. Do not send it on paper, by email or on social media. We use it only to check that the device works and delete it after the return. We recommend changing your passcode after you receive the device.
Without a passcode If you do not tell us the passcode, we can only check start-up, display, touch and charging, and functions we cannot check are not covered by the warranty.
Data Always make a backup before sending. We never view or copy your data.
"Find My" As a rule, you can leave it on. If the repair requires it to be turned off, we will contact you.
Photos We may photograph the repair process for advertising or records. You can choose whether to agree when you apply. Faces, screen content and personal information are never shown.
Personal information In line with the privacy policy, we use your information only for this repair, contacting you, returning the device, the warranty, and, if you wish, sending you news.

Warranty We tell you the warranty period with the quote. It starts on the day you receive the returned device. Devices with damage from strong impact or water are not covered by the warranty.
Check after receiving When you receive the returned device, check its appearance and operation right away. If there is any damage or fault, contact us with photos within 3 days.
Storage period We keep the device for 3 months from the day we tell you that the repair is complete or send you the quote. The same applies if a cash on delivery parcel is not collected and comes back to us (you pay the shipping for sending it again). After this period, we erase the data, take the device apart and dispose of it.
Devices we cannot accept We cannot accept stolen devices or any device that we suspect you have no legitimate right to.
Customers under 18 Customers under 18 need the consent of a parent or guardian. Fill in the parental consent form in the application form (PDF) and enclose it.
Liability Except in case of intent or gross negligence (故意または重大な過失) on our part, our liability for damages is limited to an amount equal to the price of that repair.
Language Translations of these terms are for reference only. If there is any difference, the Japanese version prevails.
