Airtel app hands India a year of Super; one Lidl Plus code hands everyone else two months — no card, no auto-renew
Airtel users, don’t miss this exciting benefit! 
Not on Airtel? The second lane is yours.
Super Duolingo = no ads, unlimited hearts, mistake review, and a better language-learning experience. 
━━━━━━ 12 MONTHS · AIRTEL · claim 3 Sep → 2 Dec 2026 ━━━━━━
Worth ₹3,120. Every active Airtel line counts: prepaid, postpaid, Wi-Fi, DTH.
Open the Airtel Thanks app · iPhone
Go to Rewards & OTTs (or Claim OTTs & More) → the Airtel Insider shelf
Tap the Super Duolingo – 12 Months FREE card
Tap Claim Now → Proceed
Log in or register on Duolingo → Super switches on 
Validity starts the day you claim, ends after 12 months, never auto-renews — Airtel’s own FAQ.
━━━━━━ 2 MONTHS · ANYWHERE · grab code by 13 Sep, redeem by 30 Sep 2026 ━━━━━━
Lidl pays for it. You need the free Lidl Plus app and a phone that receives SMS.
Install Lidl Plus · iPhone → sign up
Account → Country & Language → Germany → save (tick the terms box only, skip marketing; pick any store)
Bottom bar Lidl Plus → top tab Partnervorteile
Tap Duolingo → Vorteil sichern → copy your code 
Open duolingo.com/redeem in a browser (the app rejects it) → paste → Claim
Switch Lidl Plus back to your country — points and receipts stay.
Prepaid code: no card, ends after 2 months on its own. An active Super subscription blocks the code until that subscription ends.
🎟️ When this code dies — the rail that keeps feeding duolingo.com/redeem
- Partner codes land every few weeks: Lidl UK (Jan–Apr),
DUOBNBcodes (Apr, Jun), Marriott Bonvoy (Jul–Aug), Lidl Germany (Aug–Sep). They surface on HotUKDeals · mydealz · OzBargain · Hunt4Freebies. - Two code types in Duolingo’s terms: prepaid = no card, no yearly cap, one rule: no active subscription · extended trial = card + one per calendar year + cancel 24 h before it ends.
- Referral: profile → Invite friends → 1 week of Super per friend who starts a trial, up to 10 weeks.
🎓 Not a student? The student door still opens (2 more months, card needed)
- Fake
.edumail generators are scams. The real door: apply free to an open-admission California college — Diablo Valley College through CCCApply, real name, ID.me check with a passport (mandatory since 11 Aug 2026). The college email and acceptance letter arrive on acceptance, before any class. - Feed it to Student Beans (acceptance letter accepted) or UNiDAYS → 2-month Super trial. This one wants a card: cancel on day 1, the 2 months stay.
Learn new languages, practice daily, and make the most of your free subscription!
Claim only inside the official Airtel app or the Lidl Plus app. Neither asks for a card, so any page that does is not this offer.
