Here's how to cancel PowerX First:

**Cancellation steps (in the PowerX app):**
1. Open the app and go to **Account**
2. Open the **PowerX First management screen**
3. Tap **Stop automatic renewal**

That's it — there's no cancellation fee (en/reference/membership.md:127). Cancelling is done by stopping auto-renewal; there is no separate "cancel" button or phone procedure.

**Important things to know:**
- **You can keep using it until your contract end date.** Stopping auto-renewal doesn't cut you off immediately — your membership stays active until the expiry date (en/runbooks/membership.md, CS-066/CS-115).
- **No refunds for mid-term cancellation.** This applies to both plans; for the Annual Plan in particular, since it's a 12-month advance purchase, you can use the service until the end of the 12-month term even after cancelling, but no refund is issued (en/reference/membership.md:207).
- **During a free trial (e.g., the 90-day free campaign):** if you stop auto-renewal before the trial deadline, no fee is charged at all (en/runbooks/membership.md, CS-066/CS-125).
- **Rejoining is possible** later if you change your mind (CS-066).
- **Charging fees are separate** from the membership fee, so cancelling only stops the membership fee — any charging is still billed per kWh as usual.

**A couple of common pitfalls:**
- **Deleting the app does not cancel your membership** — your account and card info remain, and billing continues. You must stop auto-renewal in the app first (CS-115/CS-138).
- If you also want your **account and registered credit card fully deleted** (not just the membership), go to **Account > Settings > Delete Account**. Note this erases all your information (CS-115/CS-138).

If the PowerX First screen shows "Not subscribed" / "You are not currently a member," no membership fee is being charged (CS-125/CS-138).

PowerX First の解約は、PowerX アプリからご自身で手続きいただけます。

【解約（自動更新停止）の手順】
1. PowerX アプリを開き「アカウント」をタップ
2. 「PowerX First 管理画面」を開く
3. 「自動更新を停止する」を選択

（出典：/sources/ja/public-help/articles/39956798936345.md:28-32）

あわせて以下の点もご案内いたします。

- 自動更新日の確認は「アカウント > PowerX First 管理画面 > お支払いプランの確認」からご確認いただけます（同ファイル:22-26）。
- 解約手続き後も、契約期間満了日まではサービスをご利用いただけます。満了日はご入会日から1年後です（/sources/ja/public-help/articles/40046128288153.md:24, 30）。
- 解約手数料はかかりません。ただし年払いプランは先払いの一括支払いのため、途中解約によるご返金はいたしかねます（/sources/ja/reference/membership.md:131, 201）。
- 無料体験期間中に自動更新を停止された場合は、会費が発生することなく退会いただけます（/sources/ja/public-help/articles/40050080640537.md:24-25）。

なお、アプリのアンインストールだけでは解約・退会にはなりませんのでご注意ください。また、PowerX First の解約とは別にアカウント自体の削除をご希望の場合は、アプリの「設定」→「アカウントの削除」から手続き可能です（その場合も先に First の自動更新を停止してください）。登録済みのクレジットカード情報などの削除をご希望の場合は、担当部署にて対応いたしますので、お知らせください。

ご不明な点があれば、お気軽にお問い合わせください。

You cancel PowerX First yourself in the app by turning off automatic renewal — there is no separate "delete membership" button.

Steps (official Help Center)
1. Open the PowerX app.
2. Go to Account → PowerX First management screen.
3. Select "Stop automatic renewal" (Japanese UI: アカウント > PowerX First管理画面 > 自動更新を停止する).
/sources/ja/public-help/articles/40049890457497.md:20-22

What happens after you stop it
- You can keep using PowerX First benefits until your contract expiry date. /sources/ja/public-help/articles/40049890457497.md:24
- Membership auto-renews unless the cancellation is completed by the day before your next renewal date (monthly = renews for another month, annual = another year), so do it before that deadline. /sources/ja/public-help/articles/40049234480537.md:20-26
- No refunds for mid-term cancellation. Both annual and monthly plans are prepaid and are not refunded pro-rata. /sources/ja/public-help/articles/40046425200537.md:22-26
- Annual plan: because it is a 12-month prepaid purchase, you can use the service to the end of the 12-month term after cancelling, but no refund is possible. /sources/en/reference/membership.md:207
- Charging fees are separate: after cancelling you can still charge as a general user, and per-kWh charging charges still apply. /sources/ja/public-help/articles/40046425200537.md:20
- Rejoining is allowed anytime after your contract period ends. If you want a different payment plan (e.g. annual → monthly), you must cancel and then re-enrol in the desired plan; mid-term plan changes are not accepted. /sources/ja/public-help/articles/40049653349145.md:20-22, /sources/ja/public-help/articles/40046128288153.md:20-26

If you are in the 90-day free trial
- The trial auto-renews unless you yourself stop automatic renewal in the app; if you stop it within the free period, you are withdrawn with no membership fee. Note that charging during the trial is still billed at PowerX First charging rates. /sources/ja/public-help/articles/40050080640537.md:20-26
- (Separate older item: the "Try! PowerX" free-charging campaign ended 2024-11-18, needed no cancellation, and never auto-converted into PowerX First. /sources/ja/public-help/articles/38947879238169.md:34-36)

Two common pitfalls
- Uninstalling the app does not cancel anything — your account and card details remain, and renewal continues. Full account removal is a separate action (Account → Settings → Delete Account), which erases all your information and is handled by the responsible department. /sources/en/runbooks/membership.md:234, /sources/en/runbooks/membership.md:298
- If Account → PowerX First shows "You are not currently a member," no membership fee applies. /sources/en/runbooks/membership.md:266

I can't submit the cancellation for you — it has to be done in your app, and I can only confirm it once an authorized system shows auto-renewal as stopped. If you tell me whether you're on the monthly or annual plan (or in the free trial), I can point out your exact deadline.

PowerX Firstの解約は、アプリから「自動更新を停止する」操作で行っていただけます。電話や窓口での手続きは不要です。

手続き手順
PowerXアプリを開く → 「アカウント」→「PowerX First管理画面」→「自動更新を停止する」の順に選択してください（/sources/ja/public-help/articles/40049890457497.md:20-22）。

現在の更新日（有効期限）を確認したい場合は、同じ管理画面内の「アカウント」→「PowerX First管理画面」→「お支払いプランの確認」でご確認いただけます（/sources/ja/public-help/articles/39956798936345.md:24-28）。

ご留意いただきたい点
・自動更新は、次回更新日の前日までに退会手続きを完了されない限り、月払いは1ヶ月、年払いは1年分が自動更新されます（/sources/ja/public-help/articles/40049234480537.md:22-24）。お早めのお手続きをおすすめします。
・解約手続き後も、契約期間の満了日まではそのままサービスをご利用いただけます（/sources/ja/public-help/articles/40049890457497.md:24）。
・年払いは前払いの一括お支払いのため、途中解約によるご返金はいたしかねます（/sources/ja/public-help/articles/40046128288153.md:22-24）。
・90日間無料キャンペーン中の方は、期間内に「自動更新を停止」されれば会費は発生せず退会できます。停止されない場合は、お申し込み時に選ばれた年払い／月払いのプランで登録クレジットカードが決済されます（/sources/ja/public-help/articles/40050080640537.md:24-26）。
・退会後も、一般利用として充電された分については充電量に応じた料金が発生します（/sources/ja/public-help/articles/40046425200537.md:20）。

なお、PowerX Firstの解約は会員プランの解約であり、アプリのアカウント削除とは別のものです。アカウント自体の削除をご希望の場合は、アプリ内の退会手続きからご対応いただけますが、アカウント削除を選ぶと登録情報はすべて消去されます。

再入会について
退会後も、契約期間の終了後であればいつでも再入会いただけます。お支払いプラン（年払い／月払い）を変更したい場合は、一度退会手続きをされたうえで、ご希望のプランに改めてお申し込みください（/sources/ja/public-help/articles/40049653349145.md:20-22）。
